4, also known as Foreigner 4, is the fourth studio album by the British-American rock band Foreigner, released on July 2, 1981, by Atlantic Records. The album's name signifies that it is the band's fourth studio album and also the fact that the band's membership had reduced from six to four members. Musically, it showed Foreigner shifting from hard rock to more accessible mainstream rock and pop music.[10] The release of 4 coincided with the launch of MTV later that August.
4 was a commercial success worldwide, holding the No. 1 position on the Billboard 200 chart for a total of 10 weeks. It eventually sold over six million copies in the U.S. alone. Several of its singles were hits, including "Urgent", "Waiting for a Girl Like You" and "Juke Box Hero".

On Every Street is the sixth and final studio album by British rock band Dire Straits, released on 9 September 1991 by Vertigo Records internationally, and by Warner Bros. Records in the United States. The follow-up to the band's massively successful album Brothers in Arms, On Every Street reached the top of the UK Albums Chart and was also certified platinum by the RIAA.
