When it comes to generic, feel-good songs there's nothing better (or catchier) than Fleetwood Mac's Never Going Back Again. It's bouncy and just feels good. And who can argue with the simplicity of these lyrics:
She broke down and let me in
Made me see where Ive been
Been down one time
Been down two times
Im never going back again
You dont know what it means to win
Come down and see me again
Been down one time
Been down two times
Im never going back again
I know it's a really folksy song but it's really fun to play on the guitar. Maybe if you're lucky I'll write the tabs out for you--I can tell you this though, it's in F# so beware.
