The Other Side (Nina Sky EP): The Other Side is an independently released EP by Nina Sky.  After a falling-out with their record label, Polo Grounds Records, over the release of their second album "Starting Today", they decided to release this EP independently through their official website.  It features a remix of "Beautiful People", a song originally planned to be the lead single off "Starting Today".  The lead single of the EP is "You Ain't Got It (Funk That)" which samples Sagat's minor 1994 hit "Funk Dat".  "Love Song" is a cover of the US top ten pop hit by The Cure from August 1989.

Betcha Gon' Know (The Prologue): "Betcha Gon' Know (The Prologue)" is a song by American singer and songwriter Mariah Carey, from her twelfth studio album "Memoirs of an Imperfect Angel" (2009).  It was co-written and co-produced by Carey, Christopher "Tricky" Stewart, James "Big Jim" Wright and The-Dream.  Due to the success of her eleventh studio album, "E=MC²" (2008), and its lead single "Touch My Body", Carey had planned to embark on an extensive tour in support of the effort, but poor charting subsequent singles from the album prompted a halt on promotion by her label, Island Records.  It was also rumored that Carey had become pregnant and miscarried, though she never addressed it until late 2010.  She began to work on her twelfth studio effort, "Memoirs of an Imperfect Angel" throughout 2009, and it was released later on in the year.  In October 2010, Carey revealed that she had in fact been pregnant in late 2008, and that was the reason why tour plans were cancelled.
