The highest note on record is a G10 sung by Georgia Brown, a Brazilian dance/electric singer. You can hear it here (it's really something!). While a G10 is extreme, many of the coloraturas I know sing up to the 7th octave.

Billie Eilish's voice is roughly around the mezzo-soprano range. Using 'COPYCAT' as an example again, she does go right into the top soprano ranges very occasionally, but the song largely sits in that comfortable mezzo range during its chorus and the majority of the verses.
Rihanna was a light lyric soprano for most of her career but seems to have developed recently into a mezzo-soprano. How many octaves can Rihanna sing? Rihanna's vocal range is three octaves and a major third, spanning C3 – G5 – E6.
The seventh octave is the range of notes between C7 and C8. It is easier for very high coloratura sopranos to sing in this octave, but some people who are capable of singing in the bass range (like singers Adam Lopez, Virgo Degan, Nicola Sedda or Dimash Kudaibergen) can do it.
'La Campanella', which translates as 'little bell', comes from a larger work – the Grandes études de Paganini – and is famous for being one of the most difficult pieces ever written for piano. The piece's technical demands include enormous jumps for the right hand played at an uncomfortably speedy tempo.

One of the most difficult songs to whistle is "Summer" - Vivaldi (The Four Seasons) and song with lyrics - "Rap God" by Eminem.
