performance: faster load times

[mirsella]

Thanks for this awesome project ! Of course this is just feedback, and your project is already incredible !

Is your feature request related to a problem? Please describe.
Compared to the official yt music or innertube where loading times are instant (launching the app fresh to playing music from a playlist) simpmusic is a lot slower.

Describe the solution you'd like
i don't know the underlying difference for this, but maybe simpmusic could cache better some elements, like playlist data. it seems like it's loading freshly from the server everytime.

Additional context
personally, I hate waiting for things, especially when I'm out, and I want to start my music rapidly. simpmusic take me 3x more times and frustration for me to start my playlist. i would gladly screenrecord the diff if this seems exaggerated, or if it seems like a problem on my device.

thanks and have a great day !
