I downloaded an album through Itunes for my brother the other
week........ it only came down at a quality 128kbs....... the quality
was crap!
Check the other site mentioned
above - provided you're happy to have an account balance on the site
for your downloads, you can download the album in pretty much whatever
format you like - including the original wav files. Plus the prices
look a hell of a lot cheaper than iTunes. As EJO mentions though it's
priced on a per meg download. So for example to download Coldplay's
latest in wav format will cost you about $11.60, whereas to download it
at 320kbps AAC format will cost you $2.58.
