Yeah, there are lots of places selling DRM free, lossless music. However, between the lot of them they fall far short of comprehensive coverage and I frequently have to buy and rip CDs to get the music I want.
And occasionally you run into weird issues like where all online offerings are missing the pre-gap material from the CD, i.e. the bits between the tracks that are shown with a negative timestamp and which are only played when you play the disc straight through without hopping between different tracks.
Plus liner notes are often omitted online, and occasionally that, too, is a little bit of a shame, even if the main thing is of course the music itself.
