Create a Python program for managing a music store's inventory system. The inventory information is stored in a text file named "music_inventory.txt." Each line in the file represents a music album with the following format: "AlbumID, Title, Artist, Quantity, Price." The program should allow the user to add new albums, update the quantity of existing albums, and display the total value of the inventory. Ensure that the program checks for the existence of "music_inventory.txt" and handles cases where the file is empty. Utilize functions to organize your code effectively, with comments explaining each function's purpose. You can use data structures like dictionaries or lists to store and manipulate inventory data. The program should output the updated inventory information to a file named "updated_music_inventory.txt." Ex: music_inventory.txt: 301, The Dark Side of the Moon, Pink Floyd, 10, 25.99 302, Abbey Road, The Beatles, 15, 30.50 303, Thriller, Michael Jackson, 20, 20.99 (updated_music_inventory.txt after adding 5 new albums and updating The Dark Side of the Moon quantity to 15) 301, The Dark Side of the Moon, Pink Floyd, 15, 25.99 302, Abbey Road, The Beatles, 15, 30.50 303, Thriller, Michael Jackson, 20, 20.99 304, Back in Black, AC/DC, 8, 22.50 305, Rumours, Fleetwood Mac, 12, 18.75
