The mix cd still works. Honest. Girls love it man.
What you have to understand and appreciate when making the mix cd is that it's for HER, not for you though. Which can be troublesome. You have to put on tunes you think the girl will like, as oppoed to what you want her to like. The first cd you make will suck, so don't send it, and don't even think about putting two tracks from the same band on, that's the height of lame.
But get the mix cd right, and it'll be more than worth your while.
