"Sing for the Moment" was used solely because Party Ben did not have "Dream On" on hand and was on deadline for his Sixx Mixx radio show.
The mash-up first appeared as the finale of Party Ben's Sixx Mixx radio show on LIVE 105 on Friday, October 1, 2004.
[2] A new version of the mash-up was later created with "Dream On" instead of "Sing for the Moment" and was included on the compilation album The Best Mashups in the World Ever Are from San Francisco.
Vice said that the song's "beauty (...) lies in its universality", and noted it as an early example of material becoming viral.
[4] Party Ben reported having reached an agreement with "record label executives" such that all radio plays of the mashup would count as plays of the original, and that this led to the original charting a second time.
