Songs you totally thought were by somebody else

I used to think “Life is a Highway” was by INXS and had never heard of Rascal Flatts.

Similarly, I thought “Lunatic Fringe” by Red Rider was an '80s Pink Floyd song. In my defense, the guitar on that song is very Gilmour-ish.

“All The Young Dudes” was definitely David Bowie and not Mott the Hoople. I found out much later that Bowie wrote it, which explains my mistake in that one.
