Andrew W.K. is a much better piano player than people give him credit for, but when he's given free rein to do whatever he wants, he mostly plays like a 13-year-old kid. He dicks around, playing arpeggiated major chords and scales, sometimes slamming on the keys with the heel of his hand to see what'll happen, sometimes bursting into whatever song he can remember how to play (sometimes it was one of his own, sometimes it was a ragtime of some sort, once it was the Star-Spangled Banner, and once it was "Come Sail Away" by Styx, for some reason). But the thing about Andrew W.K. is that despite his semi-metal thing, his hard-partying thing, and that whole bloody-nose-cover-art thing, his music is, for the most part, strikingly innocent, catchy in an almost 1970s power pop way, and kind of childlike. His best song, "She Is Beautiful," is almost shy; it's noisy and he's snarling, sure, but it starts off with the couplet "I never knew girls existed like you // And now that I do, I'd really like to get to know you." He just wants to have fun. That's what "party" means to him; it's not really about getting drunk or doing drugs or being destructive, it's having fun in whatever way the listener interprets fun.
