YouTube Rapper Toolkit 作者： Adam

Built for rappers and singers who write over YouTube beats. Click download, and it saves the MP3 with the key, BPM, song name, and producer name — all in the filename. No more switching tabs to TuneBat, no more copying and pasting info. Everything you need is right there on YouTube.

How Key & BPM works: The extension reads the key and BPM from the video description and title — where producers put it. It's not a key finder. That said, 99% of good beats on YouTube have the key and BPM listed by the producer. The extension finds it, shows it as an orange badge, and includes it in the filename when you download.

Sort by Recently Added — One-click sort on your Watch Later playlist. Stop scrolling through old beats to find the ones you just saved.

Beat Looper — Loop any section of a beat while you write. Set start/end points with the slider or keyboard shortcuts (L = toggle loop, [ = set start, ] = set end). Your loop saves per video for 7 days, so you can come back and pick up where you left off.

MP3 Download — One-click download as MP3. Filename format: Title - Key BPM - Producer.mp3 — so when you buy the beat for licensing later, everything is organized. Requires a small free local server (2-minute setup, see GitHub).
