Swipe up for player, down for subscriptions
It would be intuitive to swipe up from the bottom of the subscriptions screen to bring up the player and then a swipe down on the player screen to go back to subscriptions.
Currently. tapping on the bottom of the subscriptions screen brings up the player and getting back to the subscriptions page is a back tap.

Actually swiping up on the player banner to go to the player screen would be cool
