The Challenge: 500 Tracks Per Month and Rising Licensing Demand
A UK-based production music library supplies background music to broadcasters, advertisers, and corporate video producers. Demand has surged with the explosion of digital content creation — the library needs 500 new tracks per month across genres (corporate, cinematic, ambient, upbeat pop, acoustic folk) to stay competitive. Commissioning from freelance composers costs an average of £180 per track for a simple 2-minute production music piece with stems. At 500 tracks monthly, that is £90,000 per month — £1.08 million annually — in composition costs alone, before accounting for A&R staff time managing 40+ freelance composers, revision cycles, and rights clearance documentation.
Cloud-based AI music generation services exist but retain licensing rights or impose usage restrictions that conflict with the library’s business model. The library needs to own 100% of the copyright on generated content to license it freely. Self-hosting the generation model ensures unambiguous ownership and avoids dependency on a third party’s terms of service.
AI Solution: Self-Hosted Music Generation Model
Open-source music generation models such as MusicGen, Stable Audio Open, or AudioCraft running on a dedicated GPU server generate high-quality audio from text prompts. A prompt like “upbeat corporate track, 120 BPM, major key, clean electric guitar, light percussion, optimistic mood, 90 seconds” produces a complete audio track with the specified characteristics. The model can generate individual stems (drums, bass, melody, pads) separately for maximum flexibility.
Fine-tuning the model on the library’s existing catalogue teaches it the specific production aesthetics, genre conventions, and audio quality standards that the library’s clients expect. A human producer reviews, curates, and occasionally adjusts generated output before it enters the catalogue.
GPU Requirements
Music generation models produce audio in real-time or faster, with quality scaling with model size and sampling steps. MusicGen-Large (3.3B parameters) generates high-fidelity 48kHz audio requiring approximately 12 GB of VRAM.
| GPU Model | VRAM | Generation Speed (90-sec track) | Monthly Batch (500 tracks) |
|---|---|---|---|
| NVIDIA RTX 5090 | 24 GB | ~45 seconds | ~6.3 hours |
| NVIDIA RTX 6000 Pro | 48 GB | ~55 seconds | ~7.6 hours |
| NVIDIA RTX 6000 Pro | 48 GB | ~38 seconds | ~5.3 hours |
| NVIDIA RTX 6000 Pro 96 GB | 80 GB | ~28 seconds | ~3.9 hours |
A single RTX 5090 generates the entire monthly catalogue in under 7 hours. Generating multiple variants per prompt (the team typically picks the best from five variations) extends this to roughly 30 hours — still comfortably within a single GPU’s weekly capacity. Private AI hosting ensures complete ownership control.
Recommended Stack
- MusicGen-Large or Stable Audio Open for text-to-music generation with stem separation.
- Demucs for additional stem separation when generating full mixes that need splitting into individual instruments.
- PyTorch with CUDA acceleration for generation and fine-tuning.
- Metadata generation using an LLM via vLLM to auto-tag tracks with genre, mood, instrumentation, tempo, and use-case keywords.
- MinIO or S3-compatible storage for the generated audio library.

Cost Analysis
Freelance composition costs £90,000 per month (£1.08M annually) for 500 tracks. AI generation with human curation reduces per-track costs from £180 to approximately £12 (covering GPU time, producer review, and mastering). Annual production costs drop to £72,000 — a saving of over £1 million per year. The library retains 100% copyright ownership with no third-party licensing dependencies.
The speed advantage is equally significant. A client requesting a custom track in a specific genre receives the first draft within hours rather than the two-week turnaround typical of human composition. This responsiveness drives premium custom-generation services that command 3-5x the standard licensing fee.
Getting Started
Generate 100 test tracks across your top five genres using the base model. Have your producers blind-evaluate AI tracks alongside human compositions for production quality, musical interest, and client suitability. Fine-tune the model on your top 2,000 catalogue tracks to align output with your aesthetic standards. Deploy for background/ambient genres first (where AI excels), expanding to more complex genres as the team builds confidence.
