Good, not too hard or easy song to learn on the guitar?

Hi, so I've been playing guitar for about four or five months. A lot of the music I listen to is either too easy (Green Day) for example the solos are incredibly easy. Or too hard, like My Chemical Romance's solo-ey songs. Or ones with distinct guitar parts (except Na Na Na) which is too easy. I can't really find any songs that I would like as they're all too hard or too easy so I was wondering, does anyone know any songs of the sort of genre that are quite a decent difficulty level? Any suggestions would be appreciated. :) Thanks.
