The **logic** of Joining and Looping the musical groups

I'm struggling to understand the "logic" as to what's missing to loop and join the musical groups together in the same list. It seems the error messages aren't of much help on this challenge. Guidance is greatly appreciated!

groups.py
musical_groups = [
    ["Ad Rock", "MCA", "Mike D."],
    ["John Lennon", "Paul McCartney", "Ringo Starr", "George Harrison"],
    ["Salt", "Peppa", "Spinderella"],
    ["Rivers Cuomo", "Patrick Wilson", "Brian Bell", "Scott Shriner"],
    ["Chuck D.", "Flavor Flav", "Professor Griff", "Khari Winn", "DJ Lord"],
    ["Axl Rose", "Slash", "Duff McKagan", "Steven Adler"],
    ["Run", "DMC", "Jam Master Jay"],
]
print("musical groups:")
group = []
for musical in musical_groups:
    print("* Group {}: ,".join(group))

# Your code here

You don't need the empty list "group", it's "musical" that you want to join.

And the instructions ask for "the members joined together with a ", " comma space as a separator", so you should use only that instead of "* Group {}: ,".
