If you're just looking for recognizable, here are a few ideas:

Dust in the Wind (great intro to Travis-style fingerpicking).
Wunderwall (cool strumming pattern)
Time of Your Life (Green Day)
Wake Me Up When September Ends (Green Day)
Tears in Heaven (Clapton)
Fire and Rain (Taylor)
I'll be Watching You (Police)

If you want to explore purely instrumental acoustic music, there are a lot of directions to take. Check out players like Larry Pattis, Peter Janson, Al Petteway, and Simon Fox. Tabs can be found for most of these.

Good luck, there's a lot of fun things to learn.
