Yeah Glen, its like when you jam a track and listen to it in the studio and think "pffft" then u play it out over a big system and its out of control,

Or the complete opposite, you layer the crap out of a track and think its sounds awesome in the studio, you play it out and its muddy as ****...

Time, place and feel - thats what its all about. Whenever you write a track, don't worry too much about it because sometimes you'll like it sometimes you'll hate it but it'll be the same track all along.
