As a guitar player. The first thing that you want to start doing is practicing scales. Once you get techniques like those down, you need to start to learn to read music.
There are a lot of Pink Floyd songs that are easy to play such as:
Wish You Were Here
Brain Damage
Interstellar Overdrive
Lucifer Sam
I myself am a crazy Rage Against The Machine fan. So these songs are kind of easy:
Bulls on Parade
Killing in the Name
Freedom
Stuff like this that sticks to only a few strings is generally easy to play.
PM me if you have anymore questions. I am always up for music discussion
