Need some updates in our existing App.

We need some small changes in our existing music App. Need following updates as attached. Please go through the requirement doc first and bid only if you can complete everything on time within the budget. Don't over bid as these are really small changes, we developed the entire project by a developer in 30$ here who promised us to be available for long term support, but I am not able to reach him now, so there is a good chance if App is successful, we will build up long term relation and we are looking for such a person only who can be available for next update projects.
