Take the Linked List from Problem 2 and let's create a linked list of songs. To achieve this, create a Song class with the following attributes: 1. Song Title 2. Song Author 3. Song Genre 4. Song Time (i.e., how long is the song in seconds) Songs should be sorted by Title. Write overloaded methods for the relational operations that compares the titles of a song. Create an Ordered Doubly Linked List and store random songs in the Linked List.
