Tbh I don’t know. I torrented lots of stuff as a kid (including music on Soulseek), but now I feel like paying for stuff. I know, weird. I suppose when I do buy music on the internet I want to support the artists. Paying for used CDs is just whatever, they’re cheap.
For music CDs? I dunno bout that (see comment above). I do borrow books a lot, if that counts.
