My long term goal to begin with was to do musical pieces and have gone to places such as film sites.
Also so musicians can better determine what instrument they think I am better on for a full set of songs.

I would not be ignorant to such tools as a click track with those professionally intended songs.
Even now I snap my fingers to imitate a drummer at the beginning of a show slapping their drum sticks when I do a track.

I just don't want to rely on click tracks through an entire duration of a song so my playing will be that much sharper.
It sure has not hurt with the smaller, easier structures.
