No one listens to classical music? Like J.S. Bach - when you need something done there is nothing better to stimulate your brain.
Or maybe Vivaldi when you feels happy or maybe some opera music?
Or maybe sometimes you feel destructive Gustav Holst's Mars seems a good choice.
Or when you feel super powerfull the music from Wagner's opera might raise you even higher.
Hold on to rock, metal, house, rap and all the other stuff, just dont' forget the old school
Btw this year for eurovision we have an opera singer. the music is nice (beautiful even - compared to other crap we usually send there), but i think it's a ripoff form HOMM5 Heaven theme. too much in music sounds the same. i compared it by palying MP3 and listening to that new song on radio.
