@Wormwood But for real, I never believe anyone actually likes every genre of music. Some people think that they have a broad range of exposure to music because they listen to Top 40s radio and have friends with a few off-beat but not too far out muscial playlists.

No, there is a whole world of musical genres out there, and you will not like them all. It is fine not to like them all, but those who make that claim are either ignorant or lying.
