MY TAKE.
I start a style with an intro, listen to the 4 breaks and style changes, listen to the pads and the ending, all never playing a note. If this reminds me of a song, I will then play the song and maybe another one or just jam with it. I then decide to keep it or not at that point. The majority of custom files are deleted. Few meet my criteria.
Good topic Heather
