MuseGen

What is MuseGen?

MuseGen is a web-based AI music generator built around a simple proposition: describe a moment, and get a song back — vocals and all. Instead of assembling loops in a DAW, users type a plain-language prompt such as "moody lofi with vinyl crackle, 85 BPM, minor key, late-night vibe," optionally paste their own lyrics or upload a reference beat, and the platform composes a complete track.

The site positions MuseGen as a combined AI music generator and AI music composer. A current V6 model is advertised as delivering steadier vocals and faster song generation. Beyond generation, MuseGen bundles a set of adjacent audio utilities — a lyrics generator, BPM detector, song key detector, MP3-to-WAV converter, audio-to-MIDI converter and an AI music prompt library — under one account, alongside a public Music Plaza and a media library for storing output.

MuseGen is aimed at people who want release-ready-sounding music without instruments or production skills, as well as at creators who want editable parts they can take into a DAW.

How MuseGen works

The workflow is presented in three stages. First, the user chooses a style by selecting genre, mood and instruments, or by writing a free-text prompt. Second, they add guidance: lyrics, style tags, tempo and mood settings, or a reference beat. Third, they iterate — extending a chorus, replacing a bass part, or merging an alternate bridge — and then export the finished mix or individual stems.

Under the hood, MuseGen reads the prompt and maps it to genre, mood, tempo and instrumentation. The engine is trained on a large music library so that melody, harmony, chords, rhythm and instrumentation fit together coherently. Each song is built from separate layers — vocals, drums, bass, melody and harmony — which is what makes part-level remixing and replacement possible. The system also follows a song's theme and structure from start to finish, and applies automatic balancing and mastering so the output arrives polished without a separate mixing session.

Main features

• Text to music and lyrics to song: generate complete tracks from a description, pasted lyrics, or both.
• AI vocals and lyrics generation: built-in vocal generation plus a dedicated lyrics assistant that writes to a described theme, mood or style.
• Genre and style coverage: pop, lo-fi, jazz, classical, EDM, hip-hop and cinematic are explicitly listed, with control over BPM and arrangement (intro, verse, chorus, bridge).
• Section-level editing: section-aligned trimming, section-safe regeneration and masking-based in-painting on individual tracks such as drums, bass, lead and vocals; users can extend a chorus, replace a bass line or merge an alternate bridge.
• Stem and MIDI export: WAV at 48k plus MIDI for DAW refinement and re-voicing with third-party plugins.
• Smart mixing and mastering: automatic balancing to studio-quality output.
• Song utility tools: AI song covers, song-length extension, BPM detection, key detection, MP3-to-WAV conversion and audio-to-MIDI.
• Music video creation: paid tiers allow MVs to be generated from a song, with HD video creation and watermark-free video downloads.
• Storage and privacy: unlimited music and video storage, plus private music creation, on paid plans.

Pricing

MuseGen offers a free trial and free credits, with paid access sold as weekly, monthly or yearly memberships. Only weekly prices are published on the pricing page; monthly and yearly rates are not shown there.

• Max — $29.99/week (listed with a reference price of $39.99, about $4.28/day, marked 40% off): 1,248 points per week, 416 music creations, 832 songs, plus the same benefit set.

The pricing page includes FAQ entries on payment methods, cancellation, refunds, auto-renewal, upgrading or downgrading, and whether paid plans include commercial rights, but the answers themselves are not reproduced in the page text.

Common use cases

• Prompt-driven songwriting: turning a mood, scene or one-line idea into a finished song with vocals.
• Lyricists without production skills: pasting a lyric sheet and receiving an arranged, sung track.
• Content and video production: generating background or feature music and building an MV from the result.
• Producer scratch pads: exporting stems and MIDI to re-voice parts with preferred plugins in a DAW.
• Iterative editing: regenerating or replacing individual parts rather than re-rolling a whole song.
• Audio utilities: detecting BPM or key, converting MP3 to WAV, or extracting MIDI from audio.

Limitations

• Point-based metering: output is capped by weekly points (248 on Pro, 1,248 on Max), which translate to stated creation and song counts; heavier use requires buying extra points.
• Sparse free-tier detail: free credits and a free trial are referenced, but the allowance, watermarks and export limits of the unpaid experience are not specified on the pages reviewed.
• Incomplete pricing: monthly and yearly options exist as tabs, but their prices and any per-term discounts are not published in the available text.
• Unanswered policy questions: refund, cancellation and auto-renewal answers are listed as FAQ headings without visible answers.
• Two concurrent tasks: generation throughput is limited to two simultaneous tasks even on the top tier.
• Prompt dependence: results are shaped by how well a description or lyrics communicate genre, mood and tempo; the site offers a prompt library partly for this reason.

Summary

MuseGen is a full-stack AI music generator: prompt or lyrics in, a sung and mastered song out, with stem/MIDI export, per-part editing and music-video creation layered on top. Its weekly memberships include commercial-use rights and unlimited storage, with the Pro tier at $9.99/week and Max at $29.99/week — though monthly and yearly pricing, free-tier limits and policy details remain undisclosed in the pages reviewed.
