These are what we call the 'YMMV items.' Things that some people find in this work. We call them 'your mileage might vary' because not everyone sees these things in the same way. This starts discussions in the trope lists, a thing we don't want. Please use the discussion page if you'd like to discuss any of these items.
YMMV: No Doubt
Ear Worm: Frequently. Stefani's "Hollaback Girl" being the worst offender.
Signature Song: "Don't Speak" for No Doubt, "Hollaback Girl" for Gwen's solo career.
Tear Jerker: "I always thought/I'd be a mom" from "Simple Kind Of Life," written at a point in time in her relationship with Bush singer Gavin Rossdale. While they eventually married and had a child, this line can still bring out the waterworks.
Don't Speak itself is a huge tear jerker. The pain is so evident in Gwen's voice, it's almost hard to listen too, god forbid you see her sing it live during the Tragic Kingdom tour, it may start the water works before she even sings.
Ex-Girlfriend is essentially the follow-up of Don't Speak. Even though the tone is mellower and slightly more upbeat, it's hard not to feel the anguish listening to it.
The largest threw up its hands after Rock Steady, which was much more pop and dance oriented than previous albums.
Another group was thoroughly disillusioned by Return of Saturn, the band's long-awaited follow-up to the absurdly popular Tragic Kingdom. Whatever ROS' appeal, it was a different sound from that heard in TK.
The "I-knew-them-when" camp abandoned the band as soon as it released its first (unsuccessful) album in 1992. This group prefers to think of No Doubt as the bad-ass punk/ska band that tore through a series of Southern California bars and tiny venues in the late 80's and early 90's.
Finally, there is a new camp that bashes their 2012 reunion Push and Shove for being WAY too poppy, electronic and less Tragic Kingdom-esque than they expected.
