J-pop:
It is the genre of music I listen to the most. The main thing that I love is the fact that the song are japanese, I find japanese to be the most beautiful language. I also don't care that I don't understand the lyrics, when I listen to music, I more often than not I don't even pay attention to what is being said, even if can understand it. I abstract the lyrics in my mind as just another instrument in the song. (btw, this doesn't mean that I don't care at all, some song sounds musically pleasing but I hate them because of the lyrics, especially with english pop song that uses playboy culture in their song, which I hate).
Vocaloid:
Some would argue that vocaloid is the same as j-pop, but I think that vocaloid song are different enough to count as it's own genre. I really love vocaloid song because I really like how they sound. It's like listening to a normal song, but the voice is more electronic, which I really like. I find that the unnatural feel of vocaloid song makes the song more interesting to listen to.
Instrumental:
This one is a bit large and is not even a genre but I don't care. I really like to listen to song containing only instrument, whatever the genre or the instrument. Not having lyrics in the song is very good because then, you don't even need to abstract the lyrics as an instrument and you can just appreciate the music in it's purest form.
