Are there any online music stores which stock a reasonably large range of albums for pop and classical music from major labels, and which let you download purchased tracks or albums in Ogg Vorbis or FLAC format? One I used to browse a while back was mp3sparks, but it seems it’s offline now. It seemed really nice in that you could specify the music format and exact encoding options yourself.
In order not to fall afoul of board rules on illegal activities, I should stress that I’m looking for legal music downloads. My legal jurisdiction is England.
