In this task you will extend the implementation of your text-based music player. (please code this in ruby)

# It is suggested that you put together code from your

# previous tasks to start this. eg:

# TT3.2 Simple Menu Task

# TT5.1 Music Records

# TT5.2 Track File Handling

# TT6.1 Album file handling

In this task you will extend the implementation of your text--ased music player. As part of the Pass level 1 requirement, your extended text-based music application must display a menu that offers the user the following options: - Menu option 1: Read in Albums - Menu option 2: Display Albums - Menu option 3: Select an Album to play - Menu option 4: Update an existing Album Menu option 1 should prompt the user to enter a filename of a file that contains the following information: - The number of albums - The first album name - The first artist name - The genre of the album - The number of tracks (up to a maximum of 15) - The name and file location (path) of each track - The album information for the remaining albums. Menu option 2 should allow the user to either display all albums or all albums for a particular genre. The albums should be listed with a unique album number which can be used in Option 3 to select an album to play. The album number should serve the role of a 'primary key' for locating an album. But it is allocated internally by your program, not by the user. Menu option 3 should prompt the user to enter the primary key (or album number) for an album as listed using Menu option 2. If the album is found the program should list all the tracks for the album, along with track numbers. The user should then be prompted to enter a track number. If the track number exists, then the system should display the message 'Playing track' then the track name, ' from album ' then the album name. You may or may not call an external program to play the track, but if not the system should delay for several seconds before returning to the main menu. Menu option 4 should allow the user to enter a unique album number and change its title or genre. The updated album should then be displayed to the user and the user is prompted to press enter to return to the main menu (you do not need to update the file at this level). At this level minimum validation is required. Just make sure your program does not crash if incorrect values are entered and that all fields have an expected value (e.g. Perhaps have a default genre of 'unknown' in case the user enters an incorrect value for genre)
