As I just said can you name some acoustic songs that would be good to play, I have an ok level at changing chords. I can play the following songs

Penny On The Floor- The Clarks
Never Too Late- Three Days Grace (it's acoustic and electric)
Through Glass- Stone Sour
Free Fallin- Tom Petty and The Heartbreakers (just learned)
Good Riddence (Time of Your Life)- Green Day.

thats it, and thanks if you suggest some.
Well as for me...

The first song I learned on my acoustic was "Plush" by Stone Temple Pilots. Should be a nice song to try at first, and I personally think it sounds great to its simplicity.
