I found this:
Nightcore is the glorified term to describe the style of speeding up Eurodance, Hands Up and Trance, which emerged in the mid 2000s[12] on YouTube. It is characterized its high-pitched vocal and tempo of between 160 and 180 beats per minute.[13] It originated in 2002 from the Norwegian DJ duo of the same name.[1][2] Since 2011, Nightcore has been massively misused to describe sped up versions of various music genres
Is this what we're talking about?
