m3u-to-tracklist.txt

// m3u to tracklist.txt
// I rip cd's and i create .m3u files that usually look like
// #EXTM3u
// #EXTsomething blahblahbalh
// 01 - artist - track
// #EXTsomething blablabalbla
//
// so I wrote this application to read the .m3u, create a .tracklist.txt
// and only copy over the lines not starting with #
