Island in the Sun by Weezer was the first song I learnt from my guitar teacher Gary Gramolini.
It is a good song for beginners since the riff consists of only 4 different chords: Em, Am, D and G.
There is a bridge that consists of D, G, D, G, C, Am, D and D, and then a guitar solo.
TAB: Island In The Sun
The music video to the song is by Spike Jonze and is epic.
