The song reached number one on the "Billboard" Alternative Songs chart, becoming their first number-one single on any Billboard chart.  "Panic Switch" was the first song by an independent artist to reach number one on the chart in 11 years.  After a one-week stay at number one, it spent 11 weeks at number two behind Linkin Park's "New Divide".  It is also their first Hot 100 entry, peaking at number 92. "Y.M.C.A." is a song by the American disco group Village People.  It was released in 1978 as the only single from their third studio album "Cruisin'" (1978).  The song reached Number 2 on the US charts in early 1979 and reached Number 1 in the UK around the same time, becoming the group's biggest hit.  It is one of fewer than 40 singles to have sold 10 million (or more) physical copies worldwide.  A medley with "Hot Cop" reached number 2 on "Billboard's" Dance Music/Club Play Singles chart. "Do You Want to Know a Secret?"  is a song by English rock group the Beatles from the 1963 album "Please Please Me", sung by George Harrison.

"Everybody Is a Star", released in December 1969, is song written by Sylvester Stewart and recorded by Sly and the Family Stone.  The song, released as the b-side to the band's 1970 single "Thank You (Falettinme Be Mice Elf Agin)", reached number one on the "Billboard" Hot 100 in February 1970 at a time when chart position for both sides of the single were measured equally and not independently.  "Star" was intended to be included on an in-progress album with "Thank You" and "Hot Fun in the Summertime"; the LP was never completed, and the three tracks were instead included on the band's 1970 "Greatest Hits" compilation.  The single was the final classic-era Family Stone recording; it would be 23 months until the next release, the single "Family Affair" in late 1971. We Invented the Remix is a remix album by P.

The album also reached number 17 on the UK Albums Chart.  The album featured the hit singles "I Need a Girl (Part 1)", which reached number 2 in the U.S., and "I Need a Girl (Part 2)", which reached number 4, a rare occurrence of both parts of the same song both becoming big hits.  This was the last album Bad Boy would release under the Arista Records label. "Thank You" is a New jack swing song released by American R&B/soul-singing group, Boyz II Men in 1995.
