There is talent to be found in nearly every genre of music, since music is so subjective you will find good song writers, good volcalists, guitar players etc etc in nearly every genre.
Op, i think i know what you mean when you say that pop songs/rap have no meaning- i have had situations where i have been listening to a song by Eluveite where they do a song in tribute to some young girl who died over 2000 years ago whreas my brother has been listening to a song by the Killers, which seems to be something about a riot van.
I am personally drawn to metal music as i like the emotional impact it conveys- it gives you a sense of power, bbecause they play loud and heavy. Many metal bands sing about fanciful things such as demons, hell, souls, epic Viking Saga's which to me i would rather listen to, as i am by nature imagantive. I will be more interested in a song about say, the battle of Pascendale, (Iron Maiden Song) or a song about pirates sailing the high seas (any song by Alestorm XD) as compared to a song about being a womanizer (madonna) or a song about a riot van (Killer's i belive)
I like music that helps me escape, reality sucks half the time, and many pop songs are to closely based in the boring old real world. That is my personal taste in music.
