"That's Life" is a single by American record producer and rapper 88-Keys featuring vocals by American rapper Mac Miller and Australian singer Sia.

Miller came up with the concept for the song stemming from a conversation he had with 88-Keys about relationships they were in at the time.

[1][2] Miller's part was recorded in New York City in February 2015, while he was working on his third studio album GO:OD AM.

[1][2] A version of the song leaked online in May 2019, incorrectly titled "Benji the Dog", with Miller alone on vocals.

"[2] "That's Life" was released as a single by Warner Records on June 20, 2019.
