Oh, here let me color code the list put in the OP
Britney Spears (I do miss back when I actually thought she enjoyed making music, but I really just want her to be happy again, even if that means never making music again.)
Shakira (Never cared for a Shakira song)
Xtina (I miss when I was naive about her personality)
Beyonce (I miss when I was naive about her fan base)
J-Lo (I don't dislike her, but I never honestly cared either)
Alicia Keys (I love IIAGY, but outside of that

)
Nelly Furtado (She had a few cute bops, but I'm not at a loss not seeing her)
Pink (She hasn't made a song I really liked in forever, but she's still around...can't really miss her.)
I can honestly say I enjoy music more now than I did back then...mostly because I've usually disliked over half the songs played on the radio...I can just use the internet to find songs I do like. With that ability, music overall just seems better to me these days.
