You are doing yourself a disservice to not give it a shot. I've disregarded tons of artists only to come back years later and find I actually really liked it.
So now, unless it's absolutely grating, I will listen to a song from a new artist in it's entirety. If it's "meh" or better, I'll listen to a second song in its entirety. Repeat until I decide if I like it.
My goal is usually to listen to an entire album, though I don't expect others to be that masochistic.
I highly recommend it. I actually did this for Sleep Token last year and decided that I did indeed I hate it but I still think it was worthwhile.
