I would just write this straight into a front page story, but unfortunately, I don't actually understand what a tracker and a sequencer are. I'll have to do a bit of reading on Wikipedia first.

Anyway, if you know what they are, there's a decent-looking article about free ones at Create Digital Music.

A really excellent post from Peter at Create Digital Music, detailing the methods for accessing the music on your portable player, and how the methods used to support DRM can make your life more difficult. I do agree with him on most points here - the use of DRM systems very rarely (never?) benefits users, and can cause some real problems.
