Shouldn't the title be "If it were written by Mark Knopfler" Dire Straits didn't write anything!!
I'm aware Mark did most of the writing but it is, as @quizzaciously said, because Dire Straits is a bigger name and does indeed get more views.
On this site everyone ofcourse knows, but to the general audience I think the name Dire Straits is substantially bigger than Mark Knopfler.
And if I did put Mark Knopfler in the title, perhaps people would expect versions that are more in line with his solo work, so that's why I went with Dire Straits.
"If performed by Dire Straits" would probably be suitable aswell.
I do more than just Dire Straits stuff though, so for some bands 'written by' would work, for some a little less. But it's quite a hassle to go and change 25 titles and thumbnails now, so I'm gonna leave it as it is for now. I don't feel like I'm misleading the audience too much with that
