Don't bother getting into metal. Just skip it and listen to a more mature genre like indie. I use to be really into metal until a couple really bad concert experience where I realized it was so immature. It made me feel tough and like nothing could take me down. That's what I really appreciate about it but the fans are horrible. They're all insane, smelly, greasy, long haired elitists.
I use to get into fights all the time with elitists who didn't like my taste in music so they tried to bully me about how I'm not a real metalhead. My last bad concert experience was what made me realize that this genre is for immature tough guys which is what I was at the time. My last metal concert was my first black metal concert. I went wearing my favorite Slipknot shirt which turned out to be a bad idea. Apparently they don't appreciate death metal so everyone was pointing and laughing at me while trying to hide it.
I didn't care so I just went and enjoyed myself. I was head banging and trying to start a mosh pit but everyone just moved away from me. After failing to start a pit for two band sets I looked around and noticed, no one was doing anything. They just stood there sometimes nodding their heads but generally just being too busy trying to be trve kvlt to enjoy themselves. Eventually in between sets some tough guy elitists got in my face, told me I didn't belong there because Slipknot isn't real metal, said something about no mosh, no core, no trends, no fun, and tried to bully me into leaving. I tried to reason with him but he was so offended about my taste in music that he wouldn't listen to reason.
Pretty quickly we ended up in a fight which I was winning because he was all talk but then I was stopped by a sharp pain in my back and when I reached back I felt a warm liquid flowing down my back and a hard smooth object. I was shocked to realize I had been stabbed and by the time I turned to see who did it, all I saw was long hair and a black shirt. Security finally arrived and they tackled me, pushing the knife and tearing the would wider. Luckily the guy that tackled me realized what happened as soon as I was on the ground and yelled at someone to call an ambulance.
I ended up needing stitches and having to stay in the hospital for a while where I had all that time to think about what happened. That's where I figured out that metal is only for immature tough guys and it was time to grow up. The guy that stabbed me was never found. It turns out there's a lot of long haired guys in a black shirts at a metal concert.
TL;DR: Metal is for immature tough guys. Don't listen to it and don't go to a concert. Listen to a more mature genre.
