I bought the Len album for 3 or 4 bucks (which does not excuse my actions, I know) 'cuz I love that "Steal my Sunshine" song. Here's the sucky part, though: the album version of that song SUCKS! It's got these stoner guys doing spoken-word "skits" between each verse! so I didn't even get the one song that I was shelling out for! I'm so dumb.
There are a couple of albums that have one song on them that I like, and every now and then I go down to the used record store down the street and listen to that song on headphones on their in-store preview system.
