Why is it when you declare Strings at first you write m in front of it like: String = mArtist; but in the constructor its just public void song (artist){ }

Non-public, non-static field names start with m.

There are used to distinguish between the class variable and the method´s variable.
For example here:
public Song ( String title, String author){ mTitle = title; mAuthor = author; }
You use "m" to distinguish between the class variable declared beforehand and the variable entered in the constructor. It read better and this way you don´t have title = title... :s
