This conversation could eventually lead to an awesome mix disc: "Crap I picked up for no apparent reason".
I used to get off the wall stuff from Columbia House -- 10 or 15 albums for a penny! You'd always run out of things you really wanted at about 7 or 8, and then take flyers on a couple of albums. That's how I ended up with
Skylarking, which I would never have checked out otherwise (not that it's off the wall, but it wasn't on my radar), and I grew to love it. It often worked out, but not always, especially if you forgot to cancel at your earliest convenience... those things were traps, and you had to be vigilant.
