Mashup (music)

A mashup (also mesh, mash up, mash-up, blend, bootleg and bastard pop/rock) is a song or composition created by blending two or more pre-recorded songs, usually by overlaying the vocal track of one song seamlessly over the instrumental track of another. To the extent that such works are "transformative" of original content, they may find protection from copyright claims under the "fair use" doctrine of copyright law.

Mashups are known by a number of different names:

Music

Music is an art form and cultural activity whose medium is sound and silence. The common elements of music are pitch (which governs melody and harmony), rhythm (and its associated concepts tempo, meter, and articulation), dynamics (loudness and softness), and the sonic qualities of timbre and texture (which are sometimes termed the "color" of a musical sound). Different styles or types of music may emphasize, de-emphasize or omit some of these elements. Music is performed with a vast range of instruments and with vocal techniques ranging from singing to rapping, and there are solely instrumental pieces, solely vocal pieces and pieces that combine singing and instruments. The word derives from Greek μουσική (mousike; "art of the Muses"). In its most general form, the activities describing music as an art form include the production of works of music (songs, tunes, symphonies, and so on), the criticism of music, the study of the history of music, and the aesthetic examination of music. Ancient Greek and Indian philosophers defined music as tones ordered horizontally as melodies and vertically as harmonies. Common sayings such as "the harmony of the spheres" and "it is music to my ears" point to the notion that music is often ordered and pleasant to listen to. However, 20th-century composer John Cage thought that any sound can be music, saying, for example, "There is no noise, only sound."

Mainstream Top 40

Mainstream Top 40 (also called Pop Songs on billboard.com and sometimes referred to as Top 40/CHR) is a 40-song music chart published weekly by Billboard Magazine which ranks the most popular songs being played on a panel of Top 40 radio stations in the United States. The rankings are based on radio airplay detections as measured by Nielsen Broadcast Data Systems (Nielsen BDS). Arbitron refers to the format as contemporary hit radio (CHR).

History

The chart debuted in Billboard Magazine in its issued date October 3, 1992, with the introduction of two Top 40 airplay charts, Mainstream and Rhythm-Crossover. Both Top 40 charts measured "actual monitored airplay" from data compiled by Broadcast Data Systems (BDS). The Top 40/Mainstream chart was compiled from airplay on radio stations playing a wide variety of music, while the Top 40/Rhythm-Crossover chart was made up from airplay on stations playing more dance and R&B music. Both charts were "born of then-new BDS electronic monitoring technology" as a more objective and precise way of measuring airplay on radio stations. This data was also used as the airplay component for Hot 100 tabulations.

Windows Live Messenger

Windows Live Messenger (formerly MSN Messenger) is a discontinued instant messaging client developed by Microsoft for Windows, Xbox 360, BlackBerry OS, iOS, Java ME, S60 on Symbian OS 9.x, and Zune HD. It connected to the Microsoft Messenger service while also having compatibility with Yahoo! Messenger and Facebook Messenger. The client was first released as MSN Messenger on July 22, 1999, and was marketed under the MSN branding until 2005 when it was rebranded under Windows Live and has since been officially known by its present name, although its previous name was still used colloquially by most of its users. In June 2009, Microsoft reported the service attracted over 330 million active users each month, placing Messenger among the most widely used instant messaging clients in the world.

Following the acquisition of Skype Technologies in May 2011, Microsoft added interoperability between Skype and Microsoft accounts, allowing Skype (which had features unique to its platform and a wider user base) to communicate with Messenger contacts. In 2013, Windows Live Messenger was discontinued and Microsoft began ceasing service to existing clients. The service in China remained active for another 18 months, and ceased operations on October 31, 2014.

It is their 7th album released on Matador and the eighth album to be given Matador's Buy Early Get Now treatment, in which it came along with a vinyl LP featuring Yo La Tengo’s Original Score from the film, Adventureland, as well as three bonus tracks as download in MP3 and FLAC.
