i alway think how a good solo or piece of music should be heard but when i try to play it i always play it otherwise and start fooling around it and never get to play it right and then forget all about it
it happens to me most when i hear a good song and try to write down it's tab

and about song writing i have an unfinished song for quite some time so far i have the very start and the very midle how will they connect? how will it end? will it end? i dont know and i dont care. if it works it works.
once my friend and i had to finish a song quickly so we forced creativity and so far it's our most successful recorded song...
