I'm in love with SizzlingKeys. It has been the best tool for iTunes for me for the past decade and I just can't live without it. :'(
It allows me to do everything I want to do with my music with a few quick key presses. For example, I can play/pause with cmd-opt-spacebar. I can rank my music with stars via option-cmd-num#0-5. Everything is so quick and smooth.
Is there anything that can compare with this for Catalina now that Apple has decided to be so cruel by tearing out 32bit support?
