A song murdered by someone.

Si Tu Vois Ma Mere...by Sidney Bechet..........strangely mangled to death by none other than Woody Allen. I became obsessed with this song after seeing  Midnight In Paris and listened to many versions
on youtube . Came across Woody's live version and it was rough 
to say the least........but his movie was excellent.

For a great "These Days" try Tom Rush.

Ahhh..Nico, the first lady of Goth.

Anything by William Shatner. He's about to release a Christmas album, so my "this version is tripe" list is about to get longer.

Tip Toe Through the Tulips by Tiny Tim has to be on a top 10 list of song covers.

Soft Cell absolutely slaughtering Gloria Jones sublime Tainted Love.

Tiffany's appalling cover of Tommy James I Think We're Alone Now.

Mariah Carey destroying Badfinger's Without You.

Van Halen's soulless attempt at The Kinks, You Really Got Me.

The Beatles lame version of Barrett Strong's Money. In fact nearly everything The Beatles covered.
