Without a doubt (no pun intended), No Doubt and Garbage are two of the most successful alternative rock acts of the '90s and beyond. Since their inceptions, the bands' frontwomen have been essential to their overall sound, image, and staying power. Gwen Stefani and Shirley Manson are gifted singers and songwriters as well as style icons, radiating grace and self-confidence wherever they go. And now, for possibly the first time, they and their groups have collaborated... in a mashup.

Here's a complete list of all the audio sources I used:

Garbage - The World Is Not Enough
No Doubt - Hella Good
Sarah McLachlan - Building a Mystery ("Worldbuilder" Soundmark V3)
