On October 18 2005, the lead single for Madonna’s Confessions on a Dance Floor album, Hung Up, was released.
Rolling Stone magazine had this to say about the release:
Going back to disco, as she always does and always should, the queen hustled up a chintzy-sounding Abba sample, a drag queen’s wet dream of a chorus, and Stuart Price’s electrobeats. The result? One of her most captivating hits ever — and thanks to those deceptively hard-hitting lyrics, one of her most personal.
The following tracks were included on the Hung Up CD maxi-single:
Radio Version
SDP Extended Vocal
Tracy Young’s Get Up and Dance Groove Edit
Bill Hamel Remix
Chus & Ceballos Remix
SDP Extended Dub
Today In Madonna History 
Hung Up is a brilliant Madonna tune-a chilling, haunted and frightening treatise about a phone call that never comes especially true now that her stepmother and brother are gone from her! Madonna is devastated and shattered and she cries alone in sadness and tears!
