Since the launch of the Amazon DRM free mp3 store, the way I shop for music has changed. I still prefer to browse for my music using iTunes. When I find something I want to buy I head over to Amazon.com mp3 store to see if its available in a higher quality DRM free version. If it is available it's usually at a cheaper price than iTunes.
Apparently this is how others do it also. I did a short post about this on Twitter and @PhillyMac_Chat sent me a link to a wonderful free script that makes this whole process easier.

Rhapsody launched its DRM Free MP3 store today. DRM Free or (Digital Rights Management Free) means that there are no restrictions on how the music can be transferred between devices such as computers such as Macs, PCs, or Linux. No restrictions on what type of media player to use either. Yes, it will work on your iPod.
