Elon Musk has built rockets, made electric cars, drilled tunnels and now, apparently, released a rap song.

The Tesla and SpaceX CEO flashed the quirky side of his personality Saturday when he posted a bizarre song on SoundCloud.

Released through what he dubbed Emo G Records, the tune is titled "RIP Harambe." It apparently memorializes the Cincinnati Zoo gorilla who was killed in 2016.

"RIP Harambe, smoking on some strong hay, in the gorilla zoo and we thinking about you," the person rapping on the song apparently says.

The track, which Musk promoted on Twitter, had about 206,000 plays as of Sunday afternoon.

Musk is known for engaging with his more than 25 million fans on Twitter. He often strays from corporate messages.
