Basically, do you download MP3's or are you against it?
Personally, I download the odd MP3 but only as a way to sample an artists/groups work. I would say that around 50% of the songs I have downloaded (around 80, though some are my brothers) I now own legitimately on album. Of the rest I dont listen to some and others I listen to but have decided not to buy the album as Im either not a big fan or consider it to be a brilliant song on an otherwise unremarkable album.
Downloading is an excellent way of sampling material, BUT imo nothing beats having the actual LP in your collection. Its very well saying "look at my MP3 collection", but I can show people my CD collection and the artwork and will be able to keep it indefinately.
(Having said this I have a load of MP3's on my computer as I burn all my CD's to put onto my MP3 player )
