I think dubstep has taken an increasing popularity in the past month at my school, or at least in the 9th grade classes.
Not a huge fan of hardcore deathpunk emo rock screamo bands, or rappers rapping about love, drugs, alcohol, violence and other things which are 100% safe and totally not influential to kids trying to fit in.
I like things like Coldplay, The Beatles and maybe the odd other band here and there, but I think I'll keep it simple.
Media forgets kids over royally, especially the internet. On the flip side, it has provided a lot of great breakthroughs for humanity.
