Sure, if you've got the time and patience to listen to the memory supercharger for 3 weeks (3 months????), wearing stereo headphones all day, by all means try it.

and when the day arrives
i'll become the sky
and i'll become the sea

and the sea will come to kiss me
for i am going
home

nothing can stop me now
