Hey Product Hunt! 👋

I built GreenGo to solve a problem every DJ hits before set: downloading tracks one by one, running them through separate BPM and key analyzers, then manually typing metadata into ID3 tags. For 50 tracks, that's hours of prep.

GreenGo does it all in one step. Paste URLs → it downloads, detects BPM & musical key locally on your machine, writes the ID3 tags, and outputs 320 kbps MP3s that Rekordbox, Serato, and Traktor pick up immediately.

A few things I'm proud of:
🎯 BPM & key detection is built-in - no external services, no API keys, runs 100% locally on your machine.
⚡ Batch mode - I regularly prep 30+ tracks at once. Paste the links, hit go, done.
🧩 Browser extension - when browsing YouTube you can send any video (or an entire playlist) straight to GreenGo with one click.

💰 One-time $24.95 purchase. No monthly fee, no usage caps, lifetime updates.
There's a 3-day free trial (no credit card). Any features you wish a tool like this had? Waveform preview, cue point suggestions, Spotify integration - I want to hear it all.
