My game will use your CC music, but title screen doesn't comport all of your required text:

"Contains music ©2019 Joshua McLean (mrjoshuamclean.com)
Licensed under Creative Commons Attribution-ShareAlike 4.0 International"

It's okay if the credit stays like the image below?

PS. The full text can be present in README file included in game pack/itch.io page.

Hey, we watched your stream playing our game, it was fun =]

However, we get the impression that you did not like the way we use your music and / or credit it in the game (sorry, English is not our native language, we may have misunderstood).
