[Bug] Using keyboard shortcut to change music source crashes Tuneful

[3raxton]

Great work on Tuneful, I am very grateful for how it has enhanced my listening experience on my Mac! I am using the built in keyboard shortcuts to control certain features of the app. When I use the keyboard shortcut I have set up to change the music source for Tuneful it crashes the app. I hope this report helps!

To get the app started again, I have to reinstall Tuneful form the downloaded .dmg.

Thanks again for the great work, I'm looking forward to seeing Tuneful grow!

Similarly to #125 this seems to be working fine for me, could you record the behaviour?
