What songs -- confirmed or unconfirmed -- you believe your fave actually shot a video for but didn't get released, mentioned or leaked?

Alternate versions of already released ones do not count.

My guesses:
- Standing on the Sun
- End of Time
- Radio (wasn't this planned to be a single together with Broken-Hearted Girl? )
- I Was Here (not the UN/Glastonbury one)
- Hip Hop Star
- Video Phone (solo)

Natalia Kills: Marlboro Lights
she said it in an interview but it was never brought out :/

Lady Gaga's Venus. There was no reason for those special albino shots she did. Something must have been filmed!

Kesha -Supernatural
