Simple guitar songs for beginning musician


I am a little better than a beginning guitar player. I would like suggestions for artists who use mostly simple guitar chords along with voice accompaniament. Songs and or artists who specialize in this genre would be appreciated. My idea is to improve my playing by playing and singing along. I hope this does not sound ridiculous.

A Neil Young songbook is one fun thing to try. You will be amazed at how many of his classics you can play with basic chord familiarity.
While on the topic, what "teach yourself guitar" PC software would you guys highly recommend for the "very beginning" guitar player. Both my daughter and I are looking to start playing acoustic guitar.
Rockethouse,great advice!Papertrail,Johney Cash has some easy ,fun songs,i also agree with Boa2,Neil Young!!!!!!!
