I just found what looks like a karaoke mp3 blog: freekaraokemusic.blogspot.com. Right now they’ve only posted torrents, but it seems promising.

Since it’s really the only good karaoke source I’ve been able to find so far, I just added it as a sidebar widget (to your right).

Here’s what to do:

1. Install a Bittorrent client (if you don’t have one): Mac / Windows
2. Try to download the biggest files first here and here.
3. Then try here and here for the fastest/most reliable downloads.
4. Then search here and here every few weeks for new stuff.
5. Closed torrent sites like this one will have special sections for karaoke, but you need to keep track of ratios.

If anyone knows of other good sources for karaoke torrents, feel free to post in the comments.
