Guitar Songs For Me To Learn?

I'm a girl who's been playing guitar for half a year now, i taught myself from reading tabs and can play most of what i look up now and i want advanced stuff to start improving from where i already am. I have an acoustic guitar because i haven't saved up enough to invest in an electric yet :( . but i really need some songs i can learn on the acoustic because im running out of ideas. i've learnt some david gilmour (wish you were here) and Led zeppelin (stairway to heaven) and this is the kind of music i really like. but any acoustic guitar songs would make me very greatful thanks xxx
