Aaaaah, with “for shits” you mean music for fun! 
(I got the literal meaning, I thought you were joking on the same pronunciation as “sheets”!) Hahaha! Ok, then the Google tool is quite easy. @nh_cham’s steps are the same I took. If you play piano and guitar by ear, with a little effort you can place notes also on this sort of piano roll (I have little musical education, the rest is all by ear).
