Bands that are, or were, really big and popular that I can’t understand the appeal: Rush - my all time most hated band by a wide margin - words can not describe how awful I think their music is.
Boston - just ughh
U2 - first album is pretty good, and it went downhill from there, and Bono is just the worst
Aerosmith - again, just ughh
For context, some of my favorite artists are:
Yo la tengo- Juana Molina - Califone - Willie Nelson - Talking Heads - Iron and Wine - Miles Davis, and many, many more
