I kind of want to say that every song from In 3D that isn't Eat It or I Lost on Jeopardy (both of which are awesome, not overrated at all, and among my favorite Weird Al songs) is underrated. Also the entire Polka Party album (mainly because it's known as one of his least-selling albums), and maybe most of the songs from his first album. And yes, I did list songs from each of those albums here.
I wanted to list some songs from later albums, but am actually having a hard time determining what songs from those albums are underrated. Maybe it's because so many songs from his last three albums got music videos while Poodle Hat only got one (which debatably counts), but I probably shouldn't be referring to songs as "underrated" just because it wasn't made into an official music video (though I didn't list any that did) or released as a single. Of course, Straight Outta Lynnwood and Mandatory Fun are two of my top four favorite Weird Al albums (the other two being In 3D and Bad Hair Day... One best from each decade), while Alpacoplypse is one of my least-favorite of his albums.
