Dweezil's got the music

The story:

This song has so many hooks that every time I heard it, I couldn't tell what the song was called so I could find it later. But I never thought "Dweezil's Got the Music" was it, so I didn't guess _that_. So finally, when it was playing at a birthday party, I asked someone what it was called, and someone told me the title, and someone told me, and that's when I finally realized what the lyric was.
