Music is subjective so I'll take this head on.
I think Eminem is undoubtedly talented to some degree - he at least writes his own music, but I find his subject matters somewhat puerile. It's a bit hard to stomach a multi millionaire complaining continually about his just terrible life.
I like an eclectic variety - mostly avant-garde, neo-folk, experimental, ambient, shoegaze, post-rock...
Metal and screamo are very, very different things. The closest metal and screamo get are 'hardcore' (Converge, for example).
Screamo, emo, hardcore and powerviolence are all very different from metal. This is a pet hate of mine - people see the likes of Bullet For My Valentine or Slipknot on MTV, shouting about their mothers tucking them into bed early and think 'God, that metal stuff is awful'. Metal is a hugely diverse and often complex genre. You've got many styles - heavy, death (with the 'growling'), black, doom, power etc etc. Like any genre, some bands will be terrible - but there is plenty to love.
And breathe
