Here's my 2 cents worth. When I was learning basic chords, I found Hotel California by the Eagles to be invaluable! It has nearly ALL the basic chords in it and they're arranged in a manner that's easy to remember. Play the entire song until you can do it in your sleep and you will know Am, E, G, D, F, C, Dm7 off by heart! Plus you can play a great tune that everybody knows. I then took these chords and started writing songs. 15 years later, I'm still at it! :)
