See. Told ya.
Anyway, I think Jacksons safe, I said pop musics decline began after 84, I'm not enough of a git not to accept that Thriller is, objectively, some good pop music.
Justin Timberlake though, seriously? Actually, mentioning him in the same sentence as Michael Jackson makes some sort of sense, as I suppose you could describe Justin Timberlake as a crap, white Michael Jackson wannabe.
Also, artistry? Seriously? Man, there ain't much artistry to be found in pop music. It's more a combination of good market research, technical proficiency and HUGE amounts of money. Vocal tuning and pitch correction are fiddly, and require expensive software to pull off well, but they're not exactly profound artistic statements or particularly talented. Arranging samples of Soft Cell and paying proffessional session musicians to rip off old Motown tunes in an arrangement dictated by a syndicate of song-writers and lyricists to pander to specific market demographics, all with no other express purpose than to make huge quantities of cash? Nah, fuck it. Sorry. Soulless garbage.
Edit: Elitism in the visual arts stems from Modernism? Say what? And I'm not arguing for elitism, I'm arguing for a universal application of the concept of artistic merit.
