I love Crooked Rain, Crooked Rain. Slanted and Enchanted is also wonderful. the last Pavement album, Terror Twilight was excellent and although you'd expect it to be pale in comparison to their earlier, classic stuff, it's very good and has at least two of the best Pavement songs on it.
Wowee Zowee and Brighten the Corners are supposedly good, too, but I have only heard scattered (good) tracks from them.
There's a newish double cd "Slanted & Enchanted Luxe & Deluxe" (horrible name) Which if you find, I suggest you get (if you already like Pavement, that is).
