Okay, so, I was remembering old movies I liked, and I remembered old movies i watched in grade 8.
I remembered we watched movies from the 30's, and we watched two movies that we're musicals.
One of them was Singin' in the rain, and there was a 2nd one i've been trying to remember for SUCH a long time but havent found anywhere.
Movies i've eliminated from it being:
White Christmas
Footlight Parade

Any help is majorly appreciated.
It's a musical from the 30's VERY alike to Singin' in the rain.

You make me feel
Like a dog, you can see, my emotions
Is this for real, i'm a man
Sinking deep, in the ocean
Well, was the other movie from the same time period as Singing in the Rain, cuz it might help to readjust your search to 50's movies as it was released in '52 (as per IMDB.com)
