My Question or Issue

When I give a voice command for Spotify to play a certain playlist it doesn't, it will play a playlist with a word that is in the playlist title. When I use Google assistant on my phone it shows the text of what I said it shows what exactly what I've said but plays something else.

For example I will say

"Ok Google, play my Happy playlist on Spotify"

And It will reply

"OK. Here's a playlist on Spotify called Happy Hits!."

Any ideas as to what I am doing wrong?
