For me personally, I like all music, but I do have some issues with some songs, for example:

Mustang Sally - every bar band and garage band in the country plays this song and when we get requests for it I cringe. There are a bazillion other songs I'd rather play

Any song with BagPipes. The hair stands on the back of my neck when I hear this instrument and I just want to scream!

Brandy, your a fine girl - maybe it's because it was played every hour on the hour on the radio when it was first released. I just cannot stand this song. I just don't like to be forced to listen to a song.

there are so many more...
