I was just watching Sister Act on TV and that got me wanting to listen to the cast album. That is what I am listening to as I am typing this and I think that it is a great cast album and a very fun and catchy score. I know that there are people on here who have said that the aren't fans of the two male songs "When I Find My Baby", and "I Could Be That Guy." However, after giving them another listen I like them better than before.
I also think that a great score is one where all the songs that are there have a reason for being there to at least advice the plot. I think that any of the songs that are part of the scores of the musicals that have won the Pulitzer can fit this category.
