okay with the song recall, just need to practice it more often, if ya learn a song but then don't play it for 3 days you wont remember it however if you play along to it at least once or twice a day you will be fine, then after a while your muscles will rememebr it for you so you don't have to think. which leads directly on to your next problem; playin the same soundin solo's. again muscle memory here, your fingers are just doin what your used to so either take a break from soloin, or listen to different styles completely for example if ya play rock solo's learn somethin like spanish style, as generally ive found playin a rock solo over a spanish backing sounds like crap so you are forced to approach it in different ways. or explore different solos without writing them out an go slow it never hurt anyone!
