Mooo! is a song by American rapper and singer Doja Cat. After originally being self-published exclusively as a music video on August 10, 2018, it became a viral internet meme and amassed over 75 million views. It was subsequently released as the lead single from the deluxe edition (and third overall) of her debut studio album Amala. The viral success of the song is considered to have been a major influence to her internet fame, ultimately "setting the tone for her career", despite being considered by herself as a "throwaway" and a "joke". In an interview with The Fader, Doja says: "I got this costume for an upcoming tour that I’m about to go on in September. I cheat sometimes and I like to wear my costumes beforehand on Live when I make music. I had this top from the costume on and didn’t know what to sing about, but the shirt was so ridiculous that I was like, 'Maybe that would be cool if I just made a song about cows.' I thought 'Nobody’s gonna care about it.' It’s just funny. It sounded kind of cute. I came up with some mooing harmonies. I had a sample that my friend (Troy NōKA) chopped for me the night before. He’s coming out with an album, and he sampled Wes Montgomery. He sent it to me and I opened it in Logic and put a beat on top of (the sample). I started the song at about 2:30 p.m. and finished the video at about 3 in the morning."
