“151 Rum” is the lead single from DiCaprio 2. It is J.I.D’s first solo release since his June 2017 single, “Hasta Luego.”

J.I.D announced the song, its single artwork, and its release date on Instagram on September 16, 2018. In the caption of the post, J.I.D wrote a heartfelt message to his fans.

“151 Rum” is named after Bacardi 151, a discontinued brand of highly alcoholic rum, which is itself named after its alcohol proof level of 151. Bacardi 151 was sold in the US from 1963 to 2016; its production was then discontinued indefinitely.

In an Instagram live video on the day of the song’s release, J.I.D gave an in-depth discussion on the song’s meaning and background.
