Just looking for some song suggestions, pretty much anything would be ok.

Martinez MPC-1C-NGL
Laney LV300H
Really anything by Three Days Grace is all in Drop D (standard - DADGBE). A few of their songs are in Drop C (CGCFAD) though. Never Too Late, Wake Up (requires capo 2nd fret), and Gone Forever are just a few that utilize Drop D standard. All songs do have electric parts, but I see no harm in playing them completely acoustic. Personally, I think Wake Up is a great one to play. Tricky and fun.
Hope this helped. If not....I tried.
