The US release includes bonus tracks "Shockwave", "Solace", and "Cool It Down". While many fans of the band enjoyed Meltdown, the album failed to make a splash in the US and was not able to build on the mild success of Free All Angels.
The Japanese release includes "Tinseltown" and "Everybody's Happy Nowadays" as bonus tracks.
In the UK, a limited edition of the album was also made, comprising two Compact Discs, one with the 11 studio recordings and one featuring live versions of the 11 new songs and live versions of three other songs ("A Life Less Ordinary", "Darkside Lightside", and "Burn Baby Burn"). The Japanese limited edition release added live versions of "Girl From Mars", "Walking Barefoot" and "Projects" to the live disc.
Tim Wheeler wrote an (almost) day by day diary during the recording of Meltdown. Tim's Studio Diary. The forum topic where Wheeler originally posted the diary (under the alias Kerouac) can be found here .
The introduction in the album's sleeve is written by American writer JT LeRoy.
The track "Evil Eye" begins with the backward message: "She's giving me the Evil Eye. Suck Satan's cock." 
In January 2007 the track "Meltdown" was remixed and covered by UK electro rock band KIK. Ash loved the punky-electro revamp of their track and gave full support for KIK to distribute and make the mix available for free download. The song was downloadable via KIK's myspace and received radio play from several UK radio stations, including BBC Sheffield and Kerrang FM!
