Context: "Hello" is a song by English singer Adele, released on 23 October 2015 by XL Recordings as the lead single from her third studio album, "25" (2015).  Adele co-wrote the song with her producer, Greg Kurstin.  "Hello" is a piano ballad with soul influences, and lyrics that discuss themes of nostalgia and regret.  Upon release, the song was well received by music critics, who compared it favourably to Adele's previous work and praised the song's lyrics and Adele's vocals.  It was recorded in London. Adele is an English singer and songwriter.  After signing a contract with record label XL Recordings in September 2006, Adele began to work on her debut studio album, "19", which was ultimately released in 2008.  At this time, the singer contributed guest vocals on the song "My Yvonne" for Jack Peñate's debut studio album "Matinée" (2007).  The first single released from "19" was "Chasing Pavements", which Adele wrote in collaboration with Eg White.  They co-wrote two other songs for the album: "Melt My Heart to Stone" and "Tired".  She also collaborated with Sacha Skarbek on the single "Cold Shoulder" and recorded a cover version of Bob Dylan's "Make You Feel My Love".  However, most of the songs were written solely by Adele, including "Best for Last", "Crazy for You", "First Love", and "My Same", as well as her debut single, "Hometown Glory".

Aggie Bonfire was a long-standing annual tradition at Texas A&M University as part of the college rivalry with the University of Texas at Austin.  For 90 years, Texas A&M students—known as Aggies—built and burned a bonfire on campus each autumn.  Known to the Aggie community simply as "Bonfire", the annual autumn event symbolized Aggie students' "burning desire to beat the hell outta t.u.", a derogatory nickname for the University of Texas.  The bonfire was traditionally lit around Thanksgiving in conjunction with festivities surrounding the annual college football game.  Although early bonfires were little more than piles of trash, as time passed the annual event became more organized.  Over the years the bonfire grew to an immense size, setting the world record in 1969.  In 1999, the Bonfire collapsed during construction, killing twelve people, eleven students and one former student, and injuring twenty-seven others.  The accident led Texas A&M to declare a hiatus on an official Bonfire.  However, since 2002, a student-sponsored coalition has constructed an annual unsanctioned, off-campus "Student Bonfire" in the spirit of its predecessor. Venus and the Razorblades were a short-lived punk band.  The Los Angeles based new wave rock band was put together by Kim Fowley after he severed professional relations with The Runaways.  Fowley sought to put together a band with a teenaged male singer and teenaged female musicians.  Roni Lee (guitarist and songwriter) joined the band early and co-wrote "I Wanna Be Where The Boys Are" performed by The Runaways as well as Venus and the Razorblades.  Roni Lee also wrote and co-wrote many of the Venus and the Razorblades songs.  She also went on to play with Mars Bonfire and Steppenwolf.  Singer/guitarist Dyan Diamond was only 14 when she auditioned for the band in 1976.  The recordings featured session players associated with Fowley projects such as guitarist Mars Bonfire, formerly of an early version of Steppenwolf; and keyboardist Billy Bizeau, formerly of The Quick, as well as members of the band itself. "Bitch I'm Madonna" is a song by American singer Madonna from her thirteenth studio album, "Rebel Heart" (2015), featuring guest vocals from rapper Nicki Minaj.  The artists co-wrote the song with MoZella, Toby Gad, Ariel Rechtshaid, Diplo, and Sophie; the latter two co-produced it with Madonna.  It was released as the third single from the album by Interscope Records on June 15, 2015, along with a number of remixes commissioned.  An EDM song, its lyrics speak about Madonna having continuous fun because she is Madonna.
