I tend to listen to things a lot and then cycle to something else as I get sick of whatever it was that I was listening to. Sort of compulsive and sort of not.
Right now I have been listening a lot to Dido, Avril Lavigne and the song 100 Years by Five for Fighting.
A little while ago it was primarily Sarah McLachlan and Shakira. Before that Norah Jones. It just sort of happens. In the past I've done the same with everything from Tori Amos to Rammstein to classical music.
Next song to play is Paul Oakenfold - Ready Steady Go which was used in an episode of Alias.
