I'm Real and Ain't It Funny, ended up becoming her biggest ever hits, with both spending several weeks at #1. However, to capitalize on this, Lopez asked Murder Inc. to remix both songs, completely changing the lyrics and melodies and adding raps from Ja Rule in both songs, and from Caddillac Tah to Ain't It Funny (Murder Remix). J.Lo's debut album 'On The 6' was released on June 1, 1999 and reached the top ten of the Billboard 200. It was about the subway line she used to take growing up in Castle Hill. The album featured the multi-week #1 lead single, If You Had My Love, as well as the top ten hit Waiting For Tonight. It also contained the Spanish language, Latin-flavored duet No Me Ames with Marc Anthony, which was an international DAN hit, though the song was never released as a single in the US. Despite this, the video received moderate airplay on the US music channels VH1 and The Box as a novelty. The album also spawned another international hit in Feelin' So Good, a hip-hop track which contained guest raps by Big Pun and Fat Joe; it failed to make the top 50 of the Billboard Hot 100. Let's Get Loud was also released as a single, and became a minor dance hit.
Her sophomore effort, J. Lo, was released in January 2001 and debuted at #1 on the Billboard 200. The lead single, Love Don't Cost A Thing was her first UK number one single, and, along with its follow-up, Play (which was written by rising teen star, Christina Milian) it became a top five hit during the year the album was released. The album's next two singles, The I'm Real and Ain't It Funny remixes were two of the biggest pop and rap hits in late 2001 and early 2002, respectively, and their more hip-hop sound gave J. Lo street credibility and brought her music to a whole new group of fans. She re-released the CD on her 32nd birthday, July 24, 2001, including Ja Rule's remixed version of I'm Real. The original version of I'm Real however, sparked controversy when it contained a sample (of Yellow Light Orchestra's Firecracker), originally planned to be used for Mariah Carey's single Loverboy. Rumors suggest this was Tommy Motolla's doing, Carey's ex-husband. Carey was forced to scrap the sample, instead using a sample of the Cameo's song Candy. The single famously flopped on radio, signaling a general downturn in Carey's career until her comeback in 2005.
In 2004, Lopez once again participated in duets with Marc Anthony, this time on his albums Amar Sin Mentiras and Valio La Pena.
After a considerable amount of time away
from the music scene, Lopez finally released her fifth studio album,
Rebirth, on March 1, 2005. Debuting at #2 on the Billboard 200 to
initially decent sales success, the album quickly fell off the charts and
making it Lopez's biggest commercial (not to mention critical) flop yet.
Despite this, the album has so-far spawned one hit in Get Right, which
reached the top twenty; however, it was greatly shunned by critics as an
almost complete rip-off of Usher's unreleased song Ride. Even so, Get
Right was a huge hit in the UK, becoming her second #1 single there. The
second single, Hold You Down, which featured Fat Joe, only barely made it
into the top 75 in the US, peaking at #64 but the track managed a peak of
#6 in the UK.
In March 2007, Jennifer Lopez released Como Ama Una Mujer and then Brave on October of the same year.
