I worry about my hearing because I listen to music as I'm sleeping, but a good general rule of thumb is moderation.....like if you're going to listen to music nonstop don't have it at a volume where you can't hear anything else...oh, and earbuds...totally not good for those ears.
But sometimes you just can't help it, like with "Evolution" or "Rule" I need to hear every sound effect in the song!
