The stuff that's easy with a pick is easy with a pick. single string rides, linear scales, chords.
The stuff that's hard with a pick are things that are more easily done with fingerstyle, such as:
Staccato single string rides (play all downstrokes and mute each note with left ring finger)
Rebel Yell - Billy Idol
String jumps:
Good Times Bad Times - Led Zeppelin
Any disco song with octave basslines
Two Tickets to Paradise - Eddie Money
All Right Now - Free
Immigrant Song - Led Zeppelin
Gallops: (bump badadump badadump badadump)
Diamonds and Rust - Judas Priest
Rolls:
Alternate up and down strokes with the very tip of the pick really fast, barely touching the string so it sounds like a smooth extended sustained note. The fresher the pick the smoother it will be.
Sorry the songs are all oldies, but you know old man gonna give old man answer.
