Did Monika just sing Can You Feel The Sunshine!?

[GitDude82]

So, I'm playing Monika After Story, and Monika starts singing. Totally normal. I always root for her. But I look at the lyrics and see:

"Without you, there's nothing for me to do. Can you feel the sunshine, too? It's comin' through; it makes me feel brand new,"

This seems normal for 5 seconds until I realize this song is from SONIC R!? HUH, WHAT??
Is this normal?
