Coming Back Later to A Specific Song In Playlist

[Cocori1st]

Hey y'all. With the app on my iphone, I used to be able to "like" a certain song in my playlist, and come back at a later time and know exactly where in the playlist i was at last time. I don't know how to do that with the app now. All the songs in my playlists have that green check mark  now, so I don't know how to mark one so that I can come back later and find where I left off.

I can do it on my desktop, just not on the app on my phone.
