"Feelin' So Good" featuring rappers Big Pun & Fat Joe is the fourth single from Jennifer Lopez's debut album "On the 6." It was written by Jennifer, Cory Rooney, Steven Standard, George Logios and Sean "Puffy" Combs, who also produced the song.
The song was released on January 25, 2000. Jennifer recorded her vocals for the song at Daddy's House Recording Studios and Sony Music Studios in New York City. The song was later edited by Jim Janik and mixed by Prince Charles Alexander. It also contains a sample of Strafe's 1984 song "Set It Off."
Around the time of the release of "Feelin' So Good," Big Pun, who was slated to join Jennifer and Fat Joe to perform the song "Saturday Night Live" passed away from a heart attack due to weight issues. Jennifer responded to his death with a statement that Big Pun was "a source of pride for the Latin community, a great artist and a great person. We will miss him terribly."
"Feelin' So Good" received positive reviews from music critics who enjoyed Jennifer going back to her roots. Newsday's Richard Torress stated that:
"Sean (Puffy) Combs shows a deft studio touch on the hip-hop jam "Feelin' so Good," with Lopez doing a good job on a track tailor-made for the talents of Mary J. Blige."
Despite flopping on the Billboard Hot 100 by only peaking at #51 on the chart, the song was considered a strong fourth single from Jennifer, charting inside the top 20 of several charts in Australia, Belgium, Canada, Germany, the Netherlands, New Zealand, Sweden, Switzerland and the United Kingdom.
The song was also a #1 dance hit, topping Billboard's Hot Dance Music/Club Play chart for a week in June of 2000, replacing Lara Fabian's song "I Will Love Again." It was also certified Gold in the United States and Australia.
