Cached songs playlist

Problem Description

When offline, recently added songs (cached songs) are useful because when data connection outside isn't available, I could still play songs. But I do still need to put songs into queue one by one.

Proposed Solution

It would be nice if you add a feature where cached songs are in a playlist so it would be easy to access and can play continuously or shuffled. Like downloaded songs but instead it's the cached songs.

Alternative Solutions

Alternative: Let cached songs from recently added songs play continuously. It gets songs from your cached songs then play continuously letting users have an uninterrupted listening when offline.

Additional Context

Like the Spotify feature where you get uninterrupted listening time. When internet connection isn't available, it automatically switch to cached songs.

I am just asking for cached songs playlist tho. It would also be nice if you also add that full feature in the future. Thank you!

No files, tests, or entry points are named. Start by locating how cached songs and downloaded songs are represented and exposed, then determine the playlist behavior and offline playback expectations. Done means cached songs are accessible as a playlist and can play continuously or shuffled without a data connection.
