How to go back to the song listened in a playlist?

[fatymid]

I have a lot of playlists., most of them are hours long. So the problem is that when I switch between them it keeps putting me at the beginning of the playlist instead of where I finished. I can't actually listen to the whole playlist

Example

Playlist A - I listened 40 songs out of 300

I switch to playlist B

Then I go back to playlist A and want to listen from 41st song, but I start from the 1st 😞
