Okay, so I was driving around earlier and Journey's "Lovin', Touchin', Squeezin'" came on the radio. Now, as everyone knows, the best part of that song is the end, when there aren't even any lyrics. If you haven't heard it in a while, listen to it here.
It got me to thinking, though. What is the best song to make extensive use of "na na na" or "la la la" or something like that? Or what is your favorite, if those are two separate things?
