Android: Blue checkmark by song

[IsaacC]

There is a blue checkmark under the album cover of Fortune Son on my playlist, it is the only song that has the checkmark. What does it mean?

Hi @IsaacC 

Welcome to community!

The blue check mark means that the track is part of your My Collection within your Pandora account.

Since this is an on-demand track, it would only be visible when you're in a Premium Session or have upgraded to a Premium subscription.
