Sort playlist tracklist on the Pare Down modal

[datguyducky]

As of now, the pared down playlist is created by adding songs from the beginning of a playlist (songs that were first added to it).
It would be best to have a button to sort playlist (on step 2 / tracklist) and then add X ammount of songs to the pared down plalyist, starting with the recently added.

Probably use the previous param returned from the Spotify playlist tracks API in order to implement that functionality.
