I've recently got into acoustic playing and have found I really enjoy playing finger-picking songs, so I'm looking for ideas on what other songs I could learn as my brain is practically defunct
I have learnt Blackbird - the Beatles, Tears in heaven - Eric Clapton and Fields of Gold - Eva Cassidy.

Any ideas would be much appreciated,
details in the fabric - jason mraz
body is a wonderland - john mayer
i'm yours - the script
Just a couple easy/intermediate ones I can think of off the top of my head

Dust In the Wind - Kansas
Why Georgia - John Mayer
Babe I'm Gonna Leave You - Led Zeppelin

Once you really get your chops together look into Tommy Emanuel, Doyle Dykes, or John Butler. There are a lot of great fingerstyle players out there if you take the time to look. These are just a couple of my favs.
Thank you for your quick replies.

I was just looking at dust in the wind, so I shall probably go for that and I'll have a look at Babe I'm gonna leave you in a sec.

Cheers again,
