Im looking for any websites that might have videos like the scientist, seven nation army, to learn how to play them on the guitar.
I guess, you should find some sites that offer guitar learning packages. Most of these sites offer some free videos too. Check this page: http://www.toptenservices.net/2009/08/19/top-ten-guitar-learning-courses/
A few courses are mentioned there and I’m pretty sure you will find some free videos. There was another site that I remember at the top of my head .. http://www.freeguitarvideos.com
