With all the artists I outgrow, it's not like I remove them from my playlists, so I will still listen to the songs I like when they come up. I just won't actively seek them.
I used to like Taylor Swift during the 1989 and reputation eras but then I just stopped caring for her. I've listened to a few of her more recent singles but didn't find anything that picked my interest again.
I also liked Lana up until the lust for life album. Everything that I listened to after that, I didn't like.
I also don't really listen to much Britney anymore. I will bop to some songs from time to time but I can't remember when was the last tome I listened to a full album.
I guess Rihanna too but then again I never really was a big fan. I just liked her songs, mostly the singles. I also was obsessed with the black eyed peas in high school but that's over since the last era that Fergie was still a part of the band.
