Why "Now That You Got It"?

I'm a big fan of Gwen Stefani, especially since their album "The Sweet Escape", which makes me sleepy due ballads à la "4 In The Morning" or "Early Winter", but also by strong hip-hop numbers such as the title track or "Yummy" that invite to dance, has convinced. So I ask myself, why Gwen after two great singles now published an average track. "Now That You Got It" barely has melody and lives on the whole only by the thumping beats. The instrumentation of this song so falls out very weak. Thus, it is for me not a catchy tune, because, let's be honest, what is a good track without succinct melody? Because the text can still be so naughty. Well, Gwen, the haste of it! Hätteste'd better publish "Early Winter", fits in any case to the season and weather.
