Since Return of Saturn flopped so badly in the UK, and "Simple Kind of Life" entered the charts at #69, this single "Bathwater", was never released in 2000.
Why No Doubt are releasing it now (remixed) is beyond me. It was not a hit in the USA, or any of the other few places it WAS released.
Maybe they are relieved their seemingly doomed Singles collection actually entered the top 10, after debuting at #46, (the temporary sales increase is due only to the shipments of Boombox anyway), so they are attempting, (yet again), to re-capture a UK fanbase.
Whatever the reasons may be, pass this one up. "Bathwater" is a mediocre song and the remix of "It's My Life" isn't anything special.
