# Chords - Yet Another Discord Music Bot |
# Chords |
||||||
|
|
||||||
 |
|
||||||
|
|
||||||
Basically everyone has written one at this point, but our little community needed one, so I made one! |
|
||||||
|
|
||||||
Here's some stuff about it: |
|
||||||
|
|
||||||
- Can play from any site that youtube-dl supports ([that's over 1800!](https://github.com/yt-dlp/yt-dlp/blob/master/supportedsites.md)) |
|
||||||
- Built-in multi-site searching via my own [MusicSearcher](https://fluff.nekojimi.moe/gitea/Nekojimi/MusicSearcher) project |
|
||||||
- More cool stuff coming soon! |
