I was wondering what you people think about classical music (as I am a classical pianist) compare to the most popular music these days?
I've stayed true to my promise to only listen to classical music my whole life so far...^.^
That's pretty sad in a sense. I thought most musicians try open themselves up to a variety of music to simply learn and find enjoyment from (in my opinion anyway). I'd suggest listening to some neo-classical metal for instance. Especially Children of Bodom one of my favorite bands, they've even re-arranged and sampled from some of Mozart's pieces for instance, the opening riff for "Red Light in My Eyes, part 2" is from Mozart's Symphony no. 25 and later there's a riff from "Requiem".
The spoken intro to the Hatebreeder album ("From now on we're enemies... You and I") comes from the movie Amadeus (1984), the story of Mozart and Salieri. The idea apparently belongs to Janne Warman, who also used a lot of samples from Amadeus in his own project, Warmen which is another neo-classical project associated with CoB.
Some other well noted classically influced metal bands and performers are Yngwie Malmsteen (though he's a bragart and a pompus *******), Michael Angelo Batio, Symphony X

, Ritchie blackmore, Randy Rhoads, Brian May, Stratovarius.
It runs deeply in metal including progressive metal, so I would suggest not simply limiting yourself to one style of music as you can find a lot of enjoyment in multiple forms, hell I know I have.
