Question:

What's the best song to sing in the shower?

I know it's an oldie but I find myself breaking into a quick chorus of 'Mrs Robinson'

Best Answer - Chosen by Asker: Psycho killer by talking heads Great song choice! Nothing wrong with the oldies and goodies. Any song you know the lyrics to.................. "Build Me Up Buttercup" by The Foundations is a personal favourite of mine. beautiful by christina aguilerra- hands down the best feel goood song ever and its totally cool for guys to jam to that too
