sooo after being a hardcore RATM fan/player, ive gotten into a sudden addiction to simple yet smooth guitar riffs. Example, John Mayer's songs "Gravity" and "Slow Dancing In A Burning Room" have been my latest addictions in guitar styles. Sounds simple, no crazy fast riffs or anything, just a smooth and a sound you can groove to. Basically, I'm lookin for songs that have guitar parts similar to the ones stated above. NOT a crazy-fast-rocking-headbanging riff, but i guess a more jazzy/soulful piece of guitar work. reccomendations?
