when did my computer get so slow?

Yes, tis true. My not-so-brand new (ok, 8mths old) iBook is becoming very creaky. It took forever to boot up this afternoon, and right now it is taking an age to import CDs. This is going to be a long afternoon, where I get cranky at my tech-so-slow, despite my very exciting high-speed internet. Question: what musica should I be downloading?
