The original font designed for MTV came in two weights: the lighter one, as seen in that screenshot, and the bolder one, on which I based Grunge Bold off of.
I'm /still/ trying to find high-quality resources for these fonts, as I plan to remake Grunge and actually start work on Grunge Light.
Work stopped in January 2018 due to the computer I housed all of the original files corrupting itself during an update.
So although Grunge (soon to be renamed upon release of the better version I'm working on) isn't exactly what you're looking for, it's part of the same unknown font family.
Sorry this is two years late, haha.

Hey, It's the third Tue of the month!

Here it is...

either Arial rounded or VAG Rounded bold

Um no it's not. I found the font. It's called "Pepsi Light" by Gerard Huerta.
