Man, the A.V. Club is spot-on almost all the fucking time.

STP is awesome. As a teenager, I loved Core the most, and hated Tiny Music. Now, I like pretty much all their stuff, but of course acknowledge that they fell off after Tiny Music. I now love Tiny Music just as much as their first two albums, and think Purple is my favorite.
Also, I think the negative reception of the third album had to do with the shift in their sound. At least that's how I felt as a dumb teenager. I thought it was poppy shit.
