The singer gives a 30-second live performance of the track, singing the song while listening to it through her headphones on a Tokyo subway.
The star previously revealed a clip of herself whistling part of the song.
'Die Young' will serve as the lead track from Ke$ha's upcoming second studio album and is expected to be released later this month.
Previously speaking about her new album, she explained: "The first two records talked more about partying, which is a great, magical part of life, but some songs on the new record are more personal and vulnerable."
