I really have a hard time perceiving what sounds good and what doesn't when it comes to mixing non-metal stuff. Sometimes I get away with it, sometimes I don't. Feel like breaking everything around me out of frustration. That's about it. Lol.
I'd say definitely make an effort to start listening to music in other genres - there are great artists in EVERY genre - pop, country, jazz, urban, you name it - the trick is to find them.
Ask some of your trusted music-nut friends (we all have them) for some recommendations and start listening.
Thanks for the feedback guys. Any recommendations for non-metal music?
