the day itunes pissed me off

Not only do I find that iTunes is a bloated application (it seems to take up a lot of memory, and takes a long time to load and quit), but I get puzzled when I log into it to buy a song and it doesn't have it. Today it was Garbage's "Special" from the ablum "Version 2.0". Why does it not have this song? I know its probably an issue with licensing or something. There have been other examples in the past. I own the cd, but its buried somewhere. I guess I'll go dig it out and rip the song so I can load it into iTunes myself.
