With all the negative publicity about DRM ever since the first music download services started up, many music services have either completely moved over to DRM free music or are in the process of doing so. However, while the majority of music on iTunes is DRM crippled (using its proprietary FairPlay copy protection system), iTunes is the leading US music retailer, so it seems like a lot of iTunes customers either don't know or even care that the music they buy enforces limitations on what the customer can do with their music.
Personally, I still prefer to buy albums on CDs instead of as downloads. I generally purchase CDs online from a variety of retailers, such as Play.com, CD Wow and Amazon, depending on the price and whether they are in stock. While this does mean that I need to wait a week or two for delivery, to me it feels better to be receiving physical products, not to mention higher quality music. A large rack of official music CDs also looks a lot prettier than even a rack of recordable CDs burnt from music obtained online.
Do you buy music online? If so, do you mind, care or even know whether the music you buy uses DRM?
