I decided I don’t like the iTunes icon very much, so I’ve made myself some new ones:
Still by LaVern Baker, Young Boy Blues by Eddie “Buster” Forehand, and We Go Together by The Moonglows, since you asked. Picked for what they look like rather than the choons – I’ve only heard one of them anyway. The Forehand is actually a fraction too big – it looks out of place in the dock. I’m using the Moonglows for the moment.
