Kurt Elling wrote a vocalese song called "Esperanto" based on the Vince Mendoza composition "Esperança". Elling explains on his album Live in Chicago (Blue Note) that the lyrics were written while he was under the impression that it was titled "Esperanto" and only later found out the original title, which is the Portuguese word for 'hope'.
The second album of former German hip hop crew Freundeskreis was titled "Esperanto". The same-called lead track was also released as a single.
A Russian band Tesla Coil released an album GV in 2014. Lyrics was partially in Esperanto. There is also a song which has a name in Esperanto - "Kirasa Kerno" (Armored Core).
