But when it comes to one question- which is my favourite music, there is no answer. Why? Because it solely depends on my mood which I am in.
I completely agree. It's hard to really pin down a favorite type of music, because for me it also depends on my mood. There are times when I'm in the mood to listen to 80s rock or pop, and other times when you'll find me listening to death metal or Marilyn Manson. My iTunes library is pretty diverse, though I'd say it's mostly comprised of rock, especially alternative and pop punk. I'm always in search of new bands or artists!
But of course, there's always classical music, which is on a level of its own. I've never loved classical music (it seems to be somewhat of an acquired taste that I've only somewhat acquired), but I can't deny that those who could compose the works were geniuses. Most of the classical music I listen to is music that I will be playing or have played on the string bass or piano.
Oh, and of course there are also musicals! They're always fun to see, and the music is usually good. It's a nice way to tell a story with music, and the music makes the play itself more interesting.
