During one of the band's recording sessions, journalist Chris Connelly asked about how the recording was coming along, to which drummer David Silveria responded that it "Sounds like the music is a little more simplified and heavier. Kind of heavier grooves, more than the last couple. So kind of more similar to the beginning, except Jon is a much better singer now, so it's all coming together."
In October 1999, Korn posted "Falling Away from Me" on their website as a free MP3 download, although it was against the advice of its attorneys. A statement on the band's site relates: "We're so psyched about [the new album] that we wanted to give all you guys, the true Korn fans — a gift from us." Also at this time, the band attempted to start an online chain email, by posting the letter online and asking fans to email the letter to 10 other people and to then sign the "I Downloaded the Korn Single For Free" guestbook on the band's site. For each person who signed, Korn donated 25 cents to the charities Childhelp USA and Children Of The Night. It raised over $250,000.
The album featured four different covers each designed by Korn fans as part of an MTV contest (the winning cover was designed by Alfredo Carlos; another album cover for special limited edition of the album features a cartoonish half-caricature for the band). There was also a fifth cover selected for the limited tour edition of the album.
Three songs from Issues were released as singles: "Falling Away from Me", "Make Me Bad", and "Somebody Someone". On December 25, 1999, "Falling Away from Me" went to number 8 on the Bubbling Under Hot 100 Singles chart. "Falling Away from Me" was on that chart for sixteen weeks. "Falling Away from Me" also went to number 7 on the Mainstream Rock Songs chart and number 7 on the Modern Rock Tracks chart. On April 22, 2000, "Make Me Bad" went to number 14 on the Bubbling Under Hot 100 Singles chart. "Make Me Bad" was on that chart for 12 weeks. "Make Me Bad" also went to number 9 on the Mainstream Rock Songs chart and number 7 on the Modern Rock Tracks chart. "Falling Away from Me" went to number 1 on MTV's Total Request Live many times during both November and December 1999.
The album received mixed to positive reviews. According to the band in the booklet that comes with Greatest Hits, Vol. 1 album, they did not want to be part of a popular trend and wanted to do their own thing. The band admits that with Brendan O'Brien working alongside them, they were more focused during recording because he didn't let them just fool around and party, so there was a lot less drinking this time around.
In 2021, it was named one of the 20 best metal albums of 1999 by Metal Hammer magazine.
The song "Dirty" ends at 3:43 and is followed up by 4 minutes and 7 seconds of static.
In the advance version, this song ends at 3:46 without the static, followed by an alternative version of "Am I Going Crazy". This version does not contain the reversed channel and has a different mix in the drums and no bass.
All Mixed Up is a KornEP released as a bonus disc alongside the album Issues featuring previously unreleased mixes and a previously unreleased song. This EP was made available for purchase separately in 2001.
