i'm a horrible person so I don't really buy cds anymore. the 150ish cds i have (or had in the past) mostly don't interest me a whole lot anymore. still have a lot of mix cds i listen to occassionally.
as for my music on my computer, i have had 1000 or so on two different computers and lost them and started over. my laptop crashed in May. starting over once again!!! so far--about 200 on my computer, and 75 or so on desktop downstairs.
