I prefer sung music by a small margin. I also enjoy instrumental music enough to listen to music in languages I don't understand.(at that point they are just another instrument.) I enjoy electro swing if done right. My top 3 favorite instruments are the violin, trumpet, and saxophone. I like the violin because if it is played well you can feel it pulling at your soul. The trumpet has tons of diversity. It can be a regal or a hardworking everybody type. The saxophone is just so alluring. So I've always liked jazz and swing, and the creative music you can achieve with electronic sound effects.
50-50. If it's an instrumental song, I like the sound of the flute the most. I also like different electronic music that has no lyrics in it. As for my favorite type, there is none. I listen to anything and everything as long as I like it. If I really had to choose, I would probably say that I like all kinds of electronic music the most. However, not so long ago, I was listening to rock'n'roll, rockabilly, and psychobilly. A bit more time ago was black metal, folk metal, progressive metal. For a brief moment, I listened to the soundtrack of HOMM4 somewhere in between. There was also a slight intervention of PSYQUI, a few mashups, and so on. It depends on my mood.
Never thought about it, but I quite like both of them, if anything, I find myself listening more to sung songs, but just by a small margin. I would say that my favorite types would be rock, metal, alternative, folk, epic music, and a lot more.
I like instrumental, but when I do listen to ones with lyrics, the lyrics are mostly in Japanese. I listen to a lot of genres with the exception of rock, metal. The various kinds of -steps and -cores don't really strike my fancy either with just a few exceptions.
