Jennifer of scriptygoddess.com writes about her (hellish) experiences with BuyMusic.com. Here's the first two (of many) problems she experienced:

First problem. After you buy an album, you need to download it. Sure, I knew that. What I didn't know is that you have to download EACH SONG INDIVIDUALLY. One click per song. With Two large sized albums with many songs on it - it can be just a LITTLE annoying.

Ok. We're compromising, right? I'll suck it up and deal.

After all the songs downloaded, I tried to play them. Second problem. Before each song plays - it has to download and verify your license. You can't mulitple select a bunch and do this. You need to do this before EACH SONG will play. [Edited to add: "Verifing your license" means another window pops up that asks for your buymusic login and password... you enter it... it thinks awhile... it thinks some more... Then it comes back and says click "play" to actually play the song...]

Ok. Getting a little annoyed here, but still willing to suck it up and deal. [scriptygoddess]

The whole experience sounds positively dreadful. Especially when I compare it to my iTunes experience, where the biggest issue was the first day or so when the system was so overloaded by everyone going there. Fortunately, I can't even look over BuyMusic.com's site because if you aren't running IE on Windows it throws you at a nice ol 'Fuck You' screen. You can't even browse the site at all. Nice and user friendly.

And to end things off, here's some other BuyMusic.com tidbits from stereoboy.org.
