The 25 Best Acting Performances by Musicians in Movies

October 5, 2018 put together a list of 'The 100 Best Acting Performances by Musicians in Movies." And it is not a coincidence that they did it just as the remake of "A Star Is Born" with Lady Gaga is coming out. In fact, the Billboard staff has already seen "A Star Is Born" and not only did Gaga make the list, she's all the way up at #4.

There were THREE rules to be eligible for the list:

1.  The artist had to be well-known for MUSIC before they were known for acting. So there's no Jamie Foxx, Lindsey Lohan, or Jennifer Lopez.

2.  The artist couldn't be playing themselves, even in a somewhat fictionalized version. So that excluded Alice Cooper, The Spice Girls, and The Beatles.

3.  Only one performance per musician-actor could be included, but it didn't necessarily have to be an Oscar-worthy, leading role.  It could be a cameo in a cult classic, IF it was deemed legendary enough.

Here's the Top 25:

1.  Cher, "Moonstruck", 1987

2.  Barbra Streisand, "The Way We Were", 1973
