Couple of bugs

Duplicate Check

• I confirm I searched for existing reports and found no duplicates.

Describe the Bug

There are couple of issues and bugs like local playlists are syncing with the youtube ones even if I turned on the syncing.

When sorting the songs, it is too difficult too sort because the sorting songs become sluggish and positioning song on top becomes a pain.
App is sluggish too. App crashes when playing in background and becomes laggy when music is played with screen off.
Syncing is not proper with youtube even if syncing is on.

Steps to Reproduce

Well Iam a beginner at programming and by the way Iam in python and AI

Expected Behavior

Sorting songs should be smooth like metrolist and archivetune and syncing should be proper too like those repos.

Log / Error Details

No response

No source file, test, or entry point is named. Start by reproducing each reported symptom on Android 16 with app version 1.5.1, separating local/YouTube playlist syncing, song sorting, and background playback, then capture logs for crashes or lag. Done should mean each issue has a reproducible case and a verified fix or a separately scoped report.
