There's definitely a negative influence it's had on writing songs with a lot of repetition. I've been writing music for a movie the past couple months, and the director is wanting a lot of repetitive and ambient tracks. However even with this I still run into problems with thinking "The chords need to change now to something completely different" or "If I don't put a new instrument in here it's going to get boring" Even though that's completely untrue. The real truth to everything is that you should be able to have diversity in your writing. Having an ability to be complex when you want and simple when you want is probably the biggest freedom to composing songs.
Doing work on this film has taught me that you can make something beautiful and interesting with only 3 tracks. Or with repetitive rhythms and lines (I will say though that if you're writing repetitive music, having a melody that's complicated will get INCREDIBLY grating after a bit). The problem with repetition is when it's done on accident or out of laziness. Like a rock song probably needs to be developing a melody in a very obvious way, but a trip hop or ambient song can develop one slow and subtly. I guess it all comes down to the context of your track, if that makes any sense.
And yeah, I agree that OCR doesn't hate repetition. I've heard a couple things from here that sound like they take influence from groups like Boards of Canada. If you listen to MHTRTC at first it seems like everything is just cut and pasted for 6 minutes a piece. But if you really listen to it you can hear that things are changing and developing, it's just happening very slowly. Like a different chord every once in awhile, or the drum sample being cut up and moved around just slightly. You shouldn't be confusing that for somebody who just copies and paste's a generic drum loop they made with some vengeance samples for 3 minutes and calls it a house song.
EDIT: Also a couple of people on OCR have seriously helped me a lot with my mixing abilities. It's a great place to learn and develop and people really shouldn't be scared of posting mixes here.
