Automated Demo Intake & A&R Scoring for Record Labels
As an artist, I sent countless demos into the void. As a label co-founder, I realized why: the listening bottleneck. Tag-per-Track isn't just a tool; it's a technical solution to a broken system, built by a musician to unblock the industry by fusing AI acoustic intelligence with real-time streaming traction.
Frequently Asked Questions
What does "A&R" (Artists & Repertoire) mean and how does Tag-per-Track help?
In the music industry (record labels, publishers, management), "A&R" stands for Artists and Repertoire. An A&R manager is essentially a talent scout: their role is to discover new artists, listen to hundreds of demo submissions, assess commercial potential, and guide creative direction.
Tag-per-Track functions as an automated digital A&R assistant:
• For independent artists & producers: it lets you benchmark your tracks before pitching, extract essential acoustic metadata (BPM, Key, Mood, Genre), and gauge commercial viability.
• For labels & managers: it automatically pre-screens incoming demo inboxes while verifying human musical authenticity against synthetic AI generators (Suno, Udio).
Which audio formats and size limits are supported?
Tag-per-Track accepts standard and uncompressed audio formats: WAV, MP3, FLAC, AIFF, M4A, and AAC. The maximum file size is 50MB with a recommended duration of up to 7 minutes (420 seconds) for near-instant processing latency.
Are my audio files stored or used to train AI models?
No. Your file is stored temporarily on our servers for the time of the analysis and deleted as soon as the report is generated: Tag-per-Track never keeps your audio and never uses your music to train AI models. Two steps rely on specialised external services, which receive audio for that sole purpose: the AI-generation check, run on a 12-second excerpt, and the optional lyrics transcription, which needs the full track. You retain 100% of your intellectual property and copyrights.
How does payment work?
Tag-per-Track offers a hybrid payment model tailored to all workflows:
• Credit Card & Apple Pay (Stripe): Ideal for studios, record labels, producers, and artists. Purchase prepaid Studio Packs in fiat (€5 for 33 credits or €15 for 100 credits) directly via Stripe Checkout using Credit Card or Apple Pay.
• USDC on Base (x402 Micro-payments): Built for autonomous AI agents, developers, and Web3 creators. Pay strictly per-use on-chain in USDC (0.15 USDC per standard analysis, 0.25 USDC with full lyrics extraction) via your Web3 wallet (Coinbase Wallet, MetaMask, etc.) with zero subscriptions.
How does the Free Trial work?
Your first standard track analysis is 100% free upon arrival, requiring no credit card or account password. The free trial is seamlessly protected via invisible Cloudflare Turnstile verification and rate-limiting to prevent automated bot abuse.
Do purchased analysis credits expire?
No, purchased credits never expire. They remain tied to your account and can be used at your own pace. If you switch devices or clear your browser cache, simply enter the email address used during Stripe Checkout to immediately restore your credit balance.
How is the A&R Score calculated and how does AI detection work?
The A&R Score is a predictive index (0 to 100) combining harmonic/dynamic richness with real-time artist traction metrics (Spotify). Concurrently, our neural detector analyzes spectral and timbre artifacts to identify synthetic music generated by Suno, Udio, or neural vocoders, certifying human musical authenticity.
