For me, YouTube allows me to revisit some of the happiest moments of my life through song. I can spend (and HAVE spent) hours surfing the site to listen to old performances of my favorite vocalists. When I'm not feelin' as terrific as I'd like to be, I immediately click to YouTube and lose myself in nothin' but JOYOUS memories!!!! Honestly, sometimes, ain't nothin' better than travellin' back down memory lane! Nothin' in the world!!!
