Sometimes I hate this forum. I had a huge response I wrote and then I had to sign in and then it erased my post. Pissed off. In summary.
Right Track. Was goofing around with you, get off the defensive.
Emo. Started in Washington DC. Americans definitely do emo and indie-emo better.
Husker Du.
Sonic Youth.
The Pixies.
Rites of Spring (considered to be the founders of emo)
Embrace.
JSBX.
Weezer (who had Pinkerton - the quintessential emo album of the 90's)
were a few of the bands mentioned.
Ska. The only time the UK had the Americans trumped in Ska was in the Second Wave of Ska, commonly called Two-Tone. We had ska before you did and thats the only reason the UK had something to build off of. Case and point - the Skatalites(this is the first wave existant in our Cajun region). Third Wave ska is completely dominated by our West Coast ska bands and further strengthened by the few greats coming from the East Coast.
Techno (and all of the other electronic sub genres you mentioned. Girlband pop is not a real genre so) Was invented in Detroit, Michigan - and existed about 10 years before the Brits got ahold of it and started using it. See:

also - since you have trouble finding artists that do these genres...

Country: Good call. England has no need for this. It is quite obvious that you folks have no idea what country is about anymore since you still use the horses on the open plain kind of thing - which says something about it's popularity over there- so fair enough.
