If you love Spotify's Discover Weekly playlist, but wish you could teach it some new tricks — you just might be in luck.

Mashable UK Social Media Producer Jennie Gale noticed Monday morning a new feature in her Discover Weekly playlist — a little heart, and a blocked sign, on the bottom left corner when a song is playing.

When you hover over the line or circle, it says "like" or "don't like."

And here's an up-close view of the Dislike. Image: screenshot/jennie gale

However, her esteemed colleagues (myself included) didn't see such a feature.

We got in touch with Spotify, who told us that they are indeed testing the like/dislike as a possible new feature for Discover Weekly, as they already have it for Daily Mix. However, there's no news on when, or if, it'll become a feature for everyone, because they are just testing it.

This is kinda fun — when you un-unlike something. Image: screenshot/jennie gale

Spotify's Discover Weekly playlist is a popular feature, and people have used it to stream just under 5 billion tracks in a year. Plenty of people have been waiting for a like/dislike function to better train their algorithm-powered recommendations, so if the feature indeed makes it through it should be popular.

Some of the tweets about it go back to 2015 and 2016...

@Spotify can you implement a "more like this" or "like" button in Discover Weekly? Most of my disc. playlist is stuff I don't listen to — D (@_Neato_) September 30, 2015

“Don’t like” button would be killer feature for @Spotify’s 'Discover Weekly'. Couple last DW playlists totally off the mark :( — Marcin Matłaszek (@mmatlaszek) February 14, 2016

And joy from the chosen few for the test today.
