It's whatever cooks your noodle isn't it. If it inspires you to play the guitar than that's great. Who knows what that can lead to.
Perhaps you should look at it as something similar to a famous pianist playing piano concerto numero whatever written by a famous writer Somebody. I'm not into music and performances like that so don't take it for granted but I believe the notes are there, they can't really change anything can they? So they have to play the right notes but they can play them in a certain unique way. At least I think that's how it works. If that comparison makes sense?
Interesting. Classical music have something that no other type of music have — the composer here always goes before the performer. It can't be "Mark Knopfler performing Chopin" (imagine that!), it always will be like "CHOPIN, Waltz Op. 64 No. 2 performed by Mark Knopfler".
In the other hand, I can't say Sultans Of Swing is something around the greatness of classical music composers. It's a good song with a great hook, lyrics and sound, but I never wanted to recreate it in any shape or form. People here know that I basically hate Sultans. I wish Mark would drop it, which he almost did. But, "twiddly bits". Oh my God...
