Aw man, it's been so long since I've heard that song.
I'm gonna listen to it after this post...
I discovered it one or two weeks ago. It's wearing off now but when I found it, I was listening to it about twenty times a day and I couldn't stop replaying it in my head and couldn't stop humming it either.
I'll follow your lead and add a new song. And, at the risk of embarrassing myself...
Looks Like We Made It, Barry Manilow
A bit lame, I know but it has a great chorus. Very memorable and explosive. The ones that make one sing carelessly, whether alone or in a group, are songs with high, memorable choruses, I find.
