[FEATURE] Add a entire playlist/album in another playlist

[Dyxux]

Problem Statement

I would like to create my own music playlist in Flow and add an existing playlist/album to it, but I have to add each song individually.

Proposed Solution

Add an option next to "Save Playlist/Album" that allows you to add it to another playlist. You could use a little "+" icon.

User Story

• As a fan of the Flow app,
  I want an option to add a playlist to another one,
  so that creating playlists becomes easier.

Priority Assessment

• Critical — I can't use Flow effectively without this
• High — I'd use this feature daily
• Medium — Nice to have, would improve my experience noticeably
• Low — Minor improvement, not urgent

@Dyxux Hello, do you merging 2 playlists in one ?

So if you had a playlist with your songs and you found a good playlist you want a option to add the songs from this playlist to yours ?

It is doable, i will give it a try soon!

[Dyxux]

Yes, that's exactly right. Would you like me to rename the issue to 'Merge playlists'?
Thank you so much, you're doing a really great job!
