This is what Lunar Boom recommends after doing some research. There is no single AI music platform that is best at everything, but the results point to a clear overall winner. Suno is the best option for most people who want complete songs, while Udio, AIVA, Soundful, and Mubert are stronger for narrower use cases.
We compared each company by price, quality, reliability, training-data legality, and output variety.
1. Suno: Best Overall AI Music Generator
Price: Suno has a free plan. Pro costs about $10 monthly or $8 per month with annual billing, while Premier costs about $30 monthly or $24 annually. Paid plans provide commercial-use rights for new songs created while subscribed. These rights do not normally apply retroactively to free-plan tracks. See Suno’s pricing and rights guidance.
Quality: Suno is the strongest all-round platform for complete songs with vocals. It handles lyrics, structure, instrumentation, and production in one workflow. Its newer models sound cleaner, although vocals can remain overly polished or emotionally flat.
Reliability: Paid plans include priority generation, but Suno publishes no clear consumer uptime guarantee. Failed outputs and repeated attempts should be expected.
Training-data legality: This is Suno’s main weakness. The Munich Regional Court ruled against Suno in a GEMA copyright case on July 31, 2026, although the decision can be appealed. Warner Music Group has separately settled with Suno and announced a licensed partnership. See the reports from Reuters and Warner Music Group.
Variety: Suno supports vocals, instrumentals, custom lyrics, uploads, extensions, stems, WAV export, and MIDI extraction.
Lunar Boom verdict: Suno is the best choice for most users, but it carries the highest visible legal risk in this comparison.
2. Udio: Best for Sound Quality and Experimentation
Price: Udio offers a free plan, Standard at $10 per month, and Pro at $30. Standard includes up to 2,400 monthly credits, while Pro includes up to 6,000. See Udio’s billing information and credit limits.
Quality: Udio is one of the strongest platforms for vocal phrasing, instrumental detail, reference styles, remixing, and precise song development. Its best outputs can sound less template-driven than competing systems.
Reliability: Udio currently disables audio, video, and stem downloads. This makes it unsuitable for distribution, client delivery, DAW production, or archiving. See Udio’s explanation of the download changes.
Training-data legality: Universal Music Group and Warner Music Group settled disputes with Udio and announced licensing partnerships. Sony filed a new case in July 2026 involving more than 30,000 allegedly copied recordings. See the UMG agreement, Warner agreement, and Sony case.
Variety: Udio supports custom lyrics, instrumentals, extensions, remixing, inpainting, style blending, references, and reusable voices.
Lunar Boom verdict: Udio is excellent for experimentation, but the download restriction prevents us from recommending it as a complete professional tool.
3. AIVA: Best for MIDI and Composition
Price: AIVA offers a free plan, Standard from €11 per month annually, and Pro from €33 annually, plus VAT. Free and Standard provide MP3 and MIDI, while Pro adds WAV and broader ownership rights. See AIVA’s pricing.
Quality: AIVA is best for cinematic, orchestral, classical, ambient, piano, and game music. Its greatest value comes from exporting MIDI and continuing the work inside a DAW.
Reliability: AIVA is more focused than Suno or Udio. Its main limitation is that unedited compositions can sound generic rather than technically unreliable.
Training-data legality: AIVA has a lower public litigation profile. However, uploaded audio or MIDI influences may be used to train AIVA under a worldwide, commercial, transferable, and perpetual license. See the AIVA license.
Variety: AIVA supports more than 250 styles, custom styles, audio and MIDI influences, piano-roll editing, MP3, MIDI, and Pro-level WAV export.
Lunar Boom verdict: Choose AIVA when editable composition matters more than realistic vocals.
4. Soundful: Best for Affordable Instrumental Stems
Price: Soundful has a free plan, with paid tiers starting around $4.99 per month and Pro around $9.99. Its public plan information has not always been fully consistent, so save the terms shown at checkout. See Soundful’s pricing.
Quality: Soundful works well for instrumental backgrounds, loops, electronic music, podcast intros, and social content. Its template approach is efficient but can become formulaic.
Reliability: The larger practical concern is inconsistent documentation around quotas, licensing, exclusivity, and copyright purchase.
Training-data legality: Soundful says it does not train on copyrighted music and instead licenses or creates its training material. This remains a company claim rather than an independent audit. See Soundful’s training-data statement.
Variety: Paid tiers provide more than 150 styles, MP3, WAV, stems, MIDI, and Ableton project exports. See Soundful’s Ableton export information.
Lunar Boom verdict: Soundful is a practical low-cost option for instrumental production, but verify the exact license before release.
5. Mubert: Best for Background Music and APIs
Price: Mubert offers Free, Creator at $14 per month, Pro at $39, and Business at $199. Creator is labelled noncommercial, while Pro covers commercial usage. See Mubert’s pricing and licensing.
Quality: Mubert is best for long background tracks, video, podcasts, streams, apps, games, exercise, and wellness content. It is not designed for memorable vocal singles.
Reliability: Its main professional advantage is the Mubert API, which supports generation and music streaming inside apps, games, and services.
Training-data legality: Mubert says it uses millions of samples from hundreds of contributing artists. This is the clearest stated provenance model here, although it is still a provider claim. See the Mubert platform.
Variety: Mubert supports text, image, mood, genre, activity, and duration inputs. Tracks can run for up to 25 minutes, and the API supports continuous music.
Lunar Boom verdict: Mubert is the best option for scalable background music, not traditional songwriting.
Final Recommendation
Lunar Boom recommends Suno for most users because it offers the best balance of quality, vocals, editing, exports, and ease of use. Choose Udio for in-platform experimentation, AIVA for MIDI and composition, Soundful for affordable instrumental stems, and Mubert for long background music or API integration.
The best platform is not simply the one with the strongest demo. It is the one that fits what you need to create, download, edit, license, and publish.
