### Current Behavior

Selecting/playing a song from offline list throws away the existing queue (and instead it adds the selected song and all the hundreds of songs in the full offline playlist).

### Expected Behavior

I wish only the songs which are **not yet** in the queue will get added instead of full unnecessary cleanup of the queue. Please note a special case - if the newly selected song is already in the queue, it should stay in the queue untouched (same position).

Rationale: the queue is a curated "playlist", frustrating to re-create over and over in case one just wanted to stop the current playing song and instead play another one without adding this other one to the queue whatsoever

### Steps To Reproduce

1. open offline list
2. add 2 songs to the queue
3. then click on any song in the offline list (this will **remove the 2 songs** from step (2) from queue and replace them with all the hundreds of offline songs in unspecified order)
