Hey Baby became No Doubt`s first Smash Hit after a long period of small hits. An interesting entering was in the UK, due entering the chart at number #2. That happend exactly 5 year after Don`t Speak`s entery in 1997. In the Billboard chart it reached such as high as Spiderwebs. (2nd single) Hella Good reached even number #1 in the remix chart but didn`t came any higher then number #13 in the Billboards. (3rd single) Underneath it All became No Doubt`s 2nd biggest hit in America by reaching number #3 (for 2 weeks) in the Billboards. (4th single) Running didn`t had the support of a maasive tour so it didn`t came any higher then #66. But it`s still good, because this single had no single version that fans could buy. So it was only on Radio airplay.
