My Question or Issue

Hello! 

I'm having some problems with certain Spotify's official playlists. 

Here what is acting wierd :

- Both "Brain Food" and "Dance Party" are acting the same.

- When I skip song, the music "fade" is way too long

- The timestamp at which the each next song start is random.

- If a song reach the end by itself, the next one timestamp at which it starts will be random too.

- Deleting cache and reinstalling Spotify do not fix the problem

I haven't look at all playlist, both those two are clearly having problems (see youtube link below).

Here what is acting normal:

- I do not have this problem using the web version of Spotify

- It doesn't happen for every playlist

- It doesn't happen with my own playlist

- It doesn't happen for albums.

I screen-recorded my phone for you to see exactly what is happening for every use case.
