By 'mix tape', I mean a collection of songs in any media.
I've done it twice, making me a extra pathetic PL. The songs I selected were carefully selected to make the girl think, "My God! I never thought old pop tunes this good existed! It makes the music that people my age listen to sound like crap! Thanks to that 'old-guy' customer for enlightening me. I must fuck him the next time he comes in!"
I doubt that either tape was ever played.
