You should make sure to put in some sort of variation, "retro music" is what I'm assuming you mean by songs from the 80's, and 70's. To see some excellent examples, try listening to "Fly like an eagle", "Take on me", "Down under", and check out a group founded in 1976 called "Tangerine Dream" for some inspiration. I wouldn't mind contributing either, but do take the time to explore a bit.
