Songs that you just have to sing

It occurred to me the other day as I was driving to work that I cannot help but to sing certain songs as I hear them on the radio - especially the one word songs like Tequila! You know, hum hum hum hum, hum hum hum hum, Tequila! I just have to sing it, even if I were sitting in church and heard in ever-so-faintly from some teenager's car's radio in the parking lot on a hot summer day. I'd still sing it!

There are others as well - Puff the Magic Dragon, for instance - you can't hear it without joining in verbally.

Of course Springsteen's "Born to Run" - I remember the college parties. Eeven the girls who didn't know the words would mumble inaduibly until the chorus kicked in, and then would loudly scream, "Baby, I was born to run - yes girl, to run!!!" Then they started to mumble again...

Another list. This time, it' sing-along songs.
