There's nothing wrong with metal. But there's nothing wrong with other styles of guitar music either. I can't limit myself to just one style.
Listen to different styles of music, learn to play some of it. Get inspired by it.
Open your mind and your @ss will follow.
Music, to me, is all about energy, vibe and emotion. If I need to get some anger out, I'll play some drop tuned metal. If I'm sad, I'll jam a blues. Most of the time I just wanna have fun and I'll play AC/DC, rock n' roll and rockabilly.
Being able to play many kinds of music will make you popular in an open mic band.
