It depends on the music and the lyrics. If you are unsure, read the lyrics of what you're listening to. Most of them do not have satanic lyrics. Only some do...usually only really hardcore stuff.
You can't dismiss it all as evil though. Some consist of poetry about the artists life and experiences, or just random stories.
I listen to rock music frequently. I can't say if I think it is a good thing to listen to it, but I do enjoy it, and have for a long time. There are worse things than music to worry about IMO.
I will add an unusual note of caution, when I was younger I had multiple occasions where I would have terrifying sleep paralysis nightmares triggered by hearing hard rock music in my dreams (Like Korn or Ozzy, etc). All would be good and well, I would be having a mundane dream, going about my dream business, then suddenly the dream rock music starts playing, next thing I know all things would go black, everything would feel frightening, and I wouldn't be able to move and my body would fall and hit the ground before I forced myself awake.
Perhaps a sign it isn't such good music? Or maybe just a weird series of dreams and too much spicy food before bed?
