Maybe Youve Been Brainwashed Too chords & tabs

Hello ladies and gentleman!
This is my first time submitting a tab so please bear with me.
This is by far my most favorite New Radicals song and one of my most favorite songs
written by Gregg Alexander himself.
His songs are amazing and soulful all the while fueled by tons of drugs, heart break and
love lost/gained.
However they are pretty easy to play if you pay close enough attention as he uses some
pretty simple chords in most of his songs.

Chords needed: F, G, Am, Am7 (Optional)

Please note that the whole way through the song the chords are just F to G to Am and
back to G and then to F and then repeat. That's it.
Alternatively on the way back to the F to start over, you can use an Am7 instead of a G.
The one playing the synthesizer on this track does it occasionally.
If I've confused you here, don't worry.
