Hehe I know exactly what you mean. With my trance/etc songs, those are expiramental. I don't know two stuffs about that genre other than that it's entirely synthesized, and has a more simple beat than most other genres. I don't believe in the whole "repetition makes stuff less enjoyable" idea. It's a pretty common topic in a lot of songs I listen to and make, but I think as long as the song is composed properly it shouldn't matter if it repeats a few times (if you can enjoy it enough for it to repeat, then I'm doing something right. =P)
Thanks Tom :D
Edit: I do have one question for you, though.. If you look at my first song.. And then my most recent.. How much would you say I have improved?
