i know one of the originals, that being the green day parody. i had started writing/planning a parody to chamillionaire's "Ridin'" just before it was leaked to be the new lead parody (believe it or not, my chorus was "talkin' nerdy" but i knew little of the song so i don't have much of a chorus but the theme was the same as Al's...he just beat me to it
). i had to researcht he other originals for the parodies but hey, i still love the album. i love allt he parodies and originals and the polka's always hold a spot for me (heck even Polka Party's Polka Party). one fo his best? definitely, i rank it as good as it's been in recent years.
i also think it's attributed to how much time is between the albums AP-93, BHD-96, RWS-99, PH-2003, SOL-2006.
if you look at alapalooza and OTDE ('92 and late '93/'94) that's way too short...three-4 years is good and typical of most artists. rushing al is like rushing robin williams or any comedian. you can't. it gets overhyped and the person comes up with lack luster shtuff.
