As told by MF Swanke:

He once bought an album (The Bambi Molesters'  Sonic Bullets: 13 From the Hip) by going to record store 40 minutes south of Tacoma, WA.  Except that he drove there twice because he spent so much time thinking about the album cover.

This album cover:

He wasn't even sure what the genre of music it was, nor anything about the band.  Rather, he just kept thinking about it.

That night he slept, and couldn't get the image out his head, and the next morning he drove the 40 minutes south back to Tacoma and promptly bought it.
