Design Changes: Material Design You (MDY)

[at-pyrix]

Is your feature request related to a problem? Please describe.
The UX of this app is good, however there are some inconsistencies in the UI. For example, the icons and the colors in the library tab are pretty inconsistent with the app's design in general.

Also, the nav bar lacks material you theming. Currently, the color of the nav bar is set to blue.

Describe the solution you'd like

1. I recommend using the Material Icons for the icon pack throughout the app. (just like it does on the nav bar)

2. For the Library tab buttons, I recommend changing the background color to match the user's system theming (MY). If that's not possible, we can try desaturating the color of the background using the Material Design 3 guidelines. The same goes for a lot of things in this app, such as the like button, the Moods and Genre and the general accent of the app.

Describe alternatives you've considered
Other apps such as Innertune (has the best UI).
