What are some complicated acoustic guitar songs that are fun to play?

I would like to know what acoustic songs are fun to play and require attention to detail when playing. Songs that use the whole fretboard such as the unplugged intro to Hotel California and Nothing Else Matters are awesome, I love learning those kinds of songs. And the intro solo to Wish You Were Here, Angie, Classical Gas, etc. I like classic rock and blues but also play modern songs like Taylor by Jack Johnson and Neon by John Mayer. I need some challenging songs that are still reasonable as I've gotten pretty good at guitar and am tired of learning songs with the basic C, G, D chords. I hate wonderwall and all the boring overplayed songs at parties. Thanks for any suggestions.
