it happens all the time, eg; i write a song and when i record it it sounds brill! so i play it over and over and it still sounds great. then i switch off, go to bed and listen again next day....then it's....oh dear, it's as if next day i'm a different person listening as a third party and so listening with a more critical ear. then i re-do it, and re-do it..ad infinitum...
lesson is; i never do a gig inebriated, never finalize a song that night, never marry a girl i've only met once...? never buy anything from a salesman who says; " i can only offer you this price now, tomorrow it goes up." ok, i'll get it on ebay. i'm not even making sense to myself now so i'll say goodnight and go to bed.......
Ask not what Chordie can do for you, but what you can do for Chordie.
