Road Trippin, F stop blues, blackbird, stairway(actually learn the tabbed pro version), stand by me, and anything Jack Johnson is decent.
Electric(rock): Alot of classic rock songs are good to learn, Led Zeppelin, ACDC, Def Leppard, Mettalica e.t.c Also some songs to really work on are cliffs of dover, little wing, sweet home Alabama, and Knocking on heavens.
NOTE: Its good to know riffs and all but you should really learn how to play full songs, especially the last four I said.
These are just my suggestions, some songs I'm currently working on such as cliffs of dover. If you need any more help or wanna talk guitar pm me.
