Hmm, tingly songs...I must say that Tom Petty's "Free Fallin'" and Bon Jovi's "Livin' on a Prayer" are up there, and "Bad" and "One" by U2 get honorable mention, but the winner is "It Must Have Been Love" by Roxette -- I have no idea why, but every time I hear that song it gets under my skin. Needless to say, it's near the top of my Guilty Pleasures list too.
