Usage of Bloc instead of Cubit at `SongPlayScreen` 

Currently, there is only one feature i.e to mark an album favorite or remove it. 
For this, we are using Cubit 

On the same screen, we have multiple options, 
To Next, Too Previous 
Pause and Play Along with different features, 
For that usage of Bloc with Events can come to handle and is more convenient to use.
