JustinGuitar Songs - Justin Sandercoe,

or his website where songs are colour code graded by difficulty

Andy Guitar - Andy Crowley. You'll have to sift through that lot yourself; or go to his website. This link is songs by artist. From the main page, you can sort by various filters.

Guitar At Work - Shane Simpson. Just search for "How to play" at that link. Superb instructional technique. Shane's got 'the touch'. Also here. Click on Download Songsheets for songs.

Shutup & Play Pick of the bunch. Andy's just the best, but material here might prove a tad more challenging if you're a rank beginner. Also here.

[br]That should get you started.
