I thought Wallflowers cover of Heroes was an original.
I thought Hootie & The Blowfish cover of Hey Hey What Can I Say was an original.
This is a very small portion of a really large list.
In my defense, growing up the only music I had access to was stuff that my grandparents made (they both played guitar, banjo, fiddle, mandolin, etc). We could not pick up any reception of a music radio station. At my mom's house, we could get a local AM station that played mostly country and Christian music.
