Can anyone recommend me an acoustic song i can learn.

I'm looking for something played with a pick (Hybrid Picking is allowed), fairly difficult, preferably instrumental, and heres the hardest part: In standard tuning

I find plenty of great acoustic instrumentals in altnerate tunings but im getting tired of having to tune my guitar

Any suggestions? (I'm already learning Clap by Steve Howe, but yea songs similar to that)
Flatpicking bluegrass. Almost anything in that genre will whip your ass just enough to force improvement.
Try eyes of the world, by grateful dead, i love playing it on acoustic, you just have to mix the two guitar parts.

It costs like ten dollars a gram
