Beheaded is the second studio album by Texas-based indie rock band Bedhead, which was released on October 24, 1996 through Trance Syndicate.
 The album was released in the United Kingdom through Rough Trade, and was reissued on compact disc format through Touch & Go Records on February 20, 2001 along with the band's other two albums "WhatFunLifeWas" and "Transaction de Novo".
 The album was included in the Numero Group's 2014 boxset "Bedhead: 1992–1998" and was also released separately on LP format.
Bedhead was an American, Texas-based indie rock band, active from 1991 to 1998.
 Members consisted of Matt and Bubba Kadane (vocals and guitar), Tench Coxe (guitar), Kris Wheat (bass), and Trini Martinez (drums).
 The band released several EPs and three LPs on Trance Syndicate, touring intermittently.
 Bedhead's music was generally subdued, with three electric guitars and one electric bass guitar over sung or spoken vocals.
 Allmusic dubbed the group "the quintessential indie rock band," and "Tiny Mix Tapes" gave their final album "Transaction de Novo" a perfect 5/5 score.
"Use Me" is the first single from the American rock band Hinder's 2008 album, "Take It to the Limit".
 It was released as a digital download through the band's website on July 15, 2008, and made available on iTunes on July 29, 2008.
 It is one of the songs that marked a change in direction in Hinder's music, transitioning from post-grunge to more of a glam metal sound, while still retaining the post-grunge and hard rock influences that were used on Hinder's previous album, "Extreme Behavior".
The song was put on as downloadable content for the video games and Rock Band 2.

 Winkler left the band in 2013, and "When The Smoke Clears" (2015) was Hinder's first album featuring new lead vocalist Marshal Dutton.
Haitian rock, or rock kreyòl, started as rock n roll in Haiti in the early 1960s.
 It was played by rock bands called "yeye" bands.
 The name "yeye" derives from the Beatles lyrical verse, "yeah, yeah, yeah", which took off in the United States and was listened to by upper class Haitian families who had access to the radio.
 Young Haitians formed small electric guitar-based bands.
 These "yeye" rock bands were short-lived, as the addition of "compas" to their repertoires resulted in a sound was called mini-jazz, or "mini-djaz" in creole.
