Amazon’s music store pretty much sucks
I _tried_ to buy a track from Amazon and it was the worst experience. Not only finding the track that I wanted was a pain in the ass (compared to iTunes). I had to download an application, that doesn’t work with Firefox. (I didn’t fiddle around with it much) So, fired up Safari and went through the whole process again.
Well, the CC they had on file was wrong. Rather then just re-checkout, I had to go through the entire process again.
Needless to say, I went back to iTunes and purchased the tracked I wanted in a fraction of the time. Screw Amazon and their tax evading ways.
