I'm listening on Grooveshark at the mo. I agree with some other posters on this forum in that I reckon the sound quality is better than Spotify. Mind you, I'm only listening through a pair of Sennheiser PX100s plugged into my laptop's headphone jack. I'm only using the free service at the mo. Sounds pretty good to me. Anyway, my question is, does anyone know how to get an album to play with the tracks in the right order. I might be missing something here (maybe it's because I'm on the free service(?)). I'm listening to Pink Floyd's The Wall but it's not much fun when the tracks are all out of sequence, as you can appreciate.
