like, as in on top of the list of many amazing musicians I know and listen to?

TBH, this is a really hard question... though, I'd say out of all artists, it's probably still the answer I would have given as a teen: SHINee and Taemin as my ult bias - though at this point, I don't really have just one bias in SHINee anymore (I love all five of them)

Also, among others, Muse and Linkin Park.
