It's not the first song I learnt but the song that inspired me to start playing was Day Old Blues by Kings of Leon. It's a gentle, quiet acoustic tune with squeeky chord changes and the chorus has a bit of an edge to it. Anyway, shortly after I started to learn I realised it was pretty difficult with a few relatively obscure chords so moved on the "usual" starters.
Yesterday I listened to the tune again and suspected it can't be that difficult so I found the chords here on chordie and I've been practicing for 2 days and I think I've got it. I'm off to bed now with a massive, broad smile on my face and can't believe I can play it!
