Schemep3 is a music playback and database program written in PLT Scheme. It can playback any audio format that MPlayer plays and read tags in any format that TagLib understands. It uses Jay McCarthy's SQLite module for database access.

If you are interested in the code, please email me at chris SQUIGGLE bowron dizzot us.
