Oooh try Maybe by Kelly Clarkson
Here would be a good and pretty easy one to learn.
It's a bit harder than what the others suggested, mainly rhythmically. Awesome song.
This is the first number I ever performed "live" (at a climber's pub in the Lake District, England - almost the height of my musical fame :) ). You can learn the chords first and strum, and change to the (reasonably simple) fingerpicking later.
NOT Stairway to Heaven. Please!
Acoustic version of this.
I play guitar myself and this song is real great to play its called gary floyd -https://m.youtube.com/watch?v=FmPtf5C9VXc It was my first song learned as its really easy only 3 chords used a,e,d and a scale that it'sself is really easy.
Another would be the End by the Doors as its a haunting composition that would sound great on an acoustic , and finally another good song to learn is the Last Time by the Rolling Stones another relatively easy song on guitar . A better version of gary floyd https://m.youtube.com/watch?v=EeT_pNegf_U
I don't play, but I love to hear "Vincent" on acoustic guitar
