Pretty comprehensive here, just a couple of comments:
As you mention No Doubt it may be worth including the fact that Stefani was part of the band
Does the caption of the sound file need to be so long? I don't think you need to write the lyrics here, as people can listen to it themselves, and it is probably not fair use to include them along with the audio sample.
Oh, and could the recording details be mentioned here, so that they do not need sourcing in the infobox? Adabow (talk · contribs) 22:50, 11 November 2010 (UTC)[reply]
This is not overlink New Wave? Already linked in the section above. TbhotchTalkC. 23:08, 11 November 2010 (UTC)[reply]
Chart performance
"...and within next eight weeks..." → ...and within the next eight weeks...
"It stayed on the chart eighteen weeks..." → It stayed on the chart for eighteen weeks...
"On other Billboard charts, the single topped the Hot Dance Club Play, as well as reached the numbers four and nine on the Adult Top 40 and Pop 100, respectively" → rewrite
"...dropping the chart on..." → ...dropping off/from the chart on...
'"Cool" became the second highest debut of the week ending September 5, 2005, at eleven' → number eleven
"...staying there only one week" → ..staying there for only one week
"...the single debuted at number eighteen soaring to number sixteen the following week..." → comma after 'eighteen'
"Moreover, in Austria..." I don't think that 'moreover' is a good choice of word here
Still a bit iffy. How about "On other Billboard charts, the single topped the Hot Dance Club Play, reached number four on the Adult Top 40 and number nine on the Pop 100."?
Place ref 32 at end of sentence, it looks odd before a dash.
Done
Maybe place inverted commas around 'cool' when you are describing Stefani's feelings in the video?
It was suggested at PR to not to do it, because it may confuse readers with the song and the word cool. TbhotchTalkC. 23:08, 11 November 2010 (UTC)[reply]
Orderer by their last name (or maybe you intended by their name?) excepting for Gwen who I think she is the important person here. TbhotchTalkC. 23:08, 11 November 2010 (UTC)[reply]
As online sources not, but since the workers go italics, they should go in that way. Personally I won't edit war with bots and automated tools which do their job. TbhotchTalkC. 23:08, 11 November 2010 (UTC)[reply]
Then place it in the publisher field Adabow (talk · contribs) 23:26, 11 November 2010 (UTC)[reply]
Same for New Zealand. If you want to link to individual charts you can use links like [1], otherwise use the Hung Medien page for the song (as you do in Australia)
There are still a couple of unneeded italics, but I won't worry about them as the rest of the article is of quite a high quality. Adabow (talk · contribs) 23:57, 11 November 2010 (UTC)[reply]

Images, NPOV, broadness all OK
Has the edit war between you and SnapSnap been sorted out?
I think it is resolved. It was about what you commented on the references, about links should or not be italised. TbhotchTalkC. 23:24, 11 November 2010 (UTC)[reply]
