"Singin in the Rain," "On the Town," "The Sound of Music," "Blue Hawaii," and probably several more that I'll remember a few hours later after posting this. I love the catchy tunes, or when a performer sings their heart out or goes above and beyond for their dance number to really sell each moment of the movie. I also love you can get sucked into these movies and forget about reality for an hour or two and it leaves you with such positive feelings at the end.
