My Question or Issue

I'm not sure if this is more ofa question or a suggestion. But there doesn't seem to be a way to get your local music that isn't available on spotify to show up in any of your normal library areas, like the Songs playlist. This is ridiculously inconvenient and I'm not sure why this isn't something that's an easier fix.
