You find some good stuff, Mumbo. The shops around here have tons of CDs but none are particularly good. You also need patience to sift through them all.
Yeah, it takes a while to look through the CDs, especially when the stores have them with the fronts facing outwards.
In one charity shop, I turn all the CDs so the spines face outwards so it's faster to look through them. They usually turn them back by the next time I visit.
I'm mainly seeking out albums that are featured in the Burnout games. I do sometimes find other interesting CDs and pick those up too.
It's usually just one single track that I want from each CD, but I refuse to buy digital download versions.
