Too many things happened this week. One of which is Lady Gaga dropped "Sour Candy," another track from her Chromatica album which featured K-pop group BLACKPINK. The song was a hit to many but others have different opinions. 

As soon as "Sour Cream" was released on Thursday, fans tweeted Lady Gaga's first-ever collaboration with a K-pop group and it started to trend worldwide. However, many also immediately noticed that another pop song has been trending despite being released in 2017. It's Katy Perry's "Swish Swish" featuring Nicki Minaj.

It appeared that it is because of the "Sour Cream" similarity with Perry's song. Fans said Gaga's latest release sampled "Swish Swish" because of their similarity. The likeness that fans are talking about can be heard on the backtracks of both songs. Perry originally sampled the melody from Maya James Coles' "What They Say." 

The claws of some Monsters and Katy Cats are out as they expressed issues about the similarity. Some of Katy's fans said they have been streaming "Swish Swish" to give the song it deserves while a fan of Gaga said, "Sour Candy" might sound like Katy's song but at least Chromatica won't have the same fate as Perry's Witness album.

Others, on the other hand, have more positive views about the matter. Many fans were excited over the fact that the two sampled the same song, regardless of who did it first. Others said it is the closest collaboration they could get from both pop superstars. 

Meanwhile, several hashtags related to Lady Gaga, BLACKPINK, and their first collab song, "Sour Cream" have been trending worldwide soon after the release. However, some BLACKPINK fans, called Blinks, tried to keep "Sour Cream" from trending too much out of respect to George Floyd. 

Apparently, they used #BlackLivesMatter instead in support of the campaign against violence and injustice. The hashtag has been trending for days after the death of George Floyd early this week. Floyd is a black man who was killed when a Minneapolis police officer kneeled on his neck for nearly eight minutes.

The fandom also decided to postpone promotional hashtag events and countdown taglines such as "SOUR CANDY IS COMING." These are usually set by fans to hype new album or song releases of their favorite artist. 

BLACKPINK Asia told Insider that since their planned hashtag events and the release of the collab coincided with the recent violence in Minneapolis, they have decided to postpone their fan activity. Instead, they would help in the promotion of a fair and just society.
