The famous American rapper Snoop Dogg promoted Psy's song that he featured in.

Today, Snoop Dogg posted on his Instagram, "Video and song is dope! Get it 1st" along with a picture.

In the picture, Psy and Snoop Dogg's faces are shown halfway and it says 'HANGOVER' and 'PSY Feat. Snoop Dogg'. The picture was also posted on Psy's Twitter yesterday.

"Hangover" is a completely different hip hop genre from his past songs "Gangnam Style" and "Gentleman" so this song is expected to show a different side of Psy. All of his songs will be released this summer.
