Suggest some acoustic songs to play

Hey,

I'm looking for new acoustic songs to play. I'm playing mainly finger picking, folk and jazz stuff. I would like some new ideas to expand my repertoire a bit (which haven't grown much in the past year).

I'm often disappointed at my quests for inspiration on the net so if anyone plays interesting songs with decently accurate tabs on the net (guitar pro and standard), the input would be appreciated.

If that can inspire anybody, my favorite guitarist is by far Bruce Cockburn (no comments on the name :whistling) and there are some crazy finger picking songs to play in his work if you want to check this out.

Here are some interesting songs to play, tabs are fairly easy to find online. I'll update it when more come to my mind.

Easy

Ben Harper (preferring The Verve version) - The Drugs Don't Work
Cat Stevens - If You Want To Sing Out
Cat Stevens - Wild World
Eric Clapton - Layla (acoustic version)
Pink Floyd - Wish You Were Here

Moderate

Beatles - Blackbird
Beatles - Here Comes The Sun
Eric Clapton - Change the World
Eric Clapton - Tears In Heaven
Kansas - Dust In The Wind
Led Zeppelin - Babe I'm Gonna Leave You
Led Zeppelin - Going To California
Led Zeppelin - Over The Hills and Far Away
Metallica - Nothing Else Matters
Pink Floyd - Is There Anybody Out There?
White Lion - When The Children Cry

Challenging

Bruce Cockburn - Foxglove
Bruce Cockburn - Sunwheel Dance
Bruce Cockburn - Train in the rain
Chet Atkins - Take Five
Eric Clapton - Signe
Simon and Garfunkel - Scarborough Fair

Any help would be appreciated.
Thanks!
