Hey Billy,
Strange place to ask this question indeed :)
These are known issues with Android phones full of default Samsung's bloatware. I'm guessing your phone isn't rooted which would make the solution to your problem a little more difficult. Basically, you're gonna need to install a third-party app to be able to select which player is used and what other actions your phone will take when connected to Bluetooth, such as Bluetooth connect & Play, but there are many other apps that can do the same job.
