Well my long time favorite No Doubt song has always been 'Bathwater'... Its so unique, it speaks to woman who are in love so strongly, and the horns on it are awesome...... BUT, now that my young daughter Gwen (Yep, named after Ms. Stefani...and her older brother is Gavin..lol!!), has turned into such a fan herself, and walks around the house constantly singing 'Settle Down' I will have to say that that song is my new favorite ;) I have created a new generation of fandom with her... Yaya!!
