Let's break the task's wording apart:

Can you loop through each group leads to: for group in musical_groups:

and output the members leads to: print(group)

joined together with a ", " comma space as a separator (means you need to do a join of ", " to the group) and so modifies print(group) to be: print(", ".join(group))

Hope this helps!

This probably has to be the best comprehensive answer I've gotten. Thank you so much.

Thanks. It kind of just came to me to break down the challenge like that. Kind of the way we should code - break it all down into simpler stuff. Glad I could be of help.
