I don't think anyone has appreciated what Coldplay did with their MV for The Scientist. In which Chris Martin really had to learn to sing the song backwards for the MV.

Here's what Director Jamie Thraves said on his interview with MTV way back on 2003

"I had this idea that I wanted to do a story that's tragic but starts off happy and ends happy, and the video is about rewinding to that happy ending,"

Thraves needed to find a new way to tell a narrative story that moved forward even as the action moved backward.

"The original idea was a straight narrative without the lead singer in the video," said Thraves. "But Chris wanted to be in the video and he was really excited to learn how to sing the song backward."

"He got a tape of the song recorded backward and he listened to it over and over. He's a very passionate guy, so he got really into it. What we learned later on is about the problems with phonetics, because you have to be very careful with the lip movement so that when you end on a sound your mouth is formed in the right way."

I think this would be always the most impressive music video in my book, ALWAYS. The dedication Chris Martin put man, I cant even think how he learned all of that.
