autocorrect and noredirect

Hello. I try to use API for grab some info about songs, with Track.getInfo method. The string is:
'http://ws.audioscrobbler.com/2.0/?method=track.getinfo&api_key=XXX&autocorrect[1]&artist=White Stripes&track=Seven Nation Army'
In response I get <name>White Stripes</name> and <url>http://www.last.fm/music/+noredirect/White+Stripes</url>;. This tell me that param 'autocorrect' doesn't work: correct name of artist is 'The White Stripes'. Also, there is '+noredirect/' in song and artist url.
I need to get corrected name - how can I get it?

'http://ws.audioscrobbler.com/2.0/?method=track.getinfo&api_key=XXX&autocorrect1&artist=White%20Stripes&track=Seven%20Nation%20Army' and 'http://ws.audioscrobbler.com/2.0/?method=track.getinfo&api_key=XXX&artist=White%20Stripes&track=Seven%20Nation%20Army' both gives me the same result - incorrect '<name>White Stripes</name>' and path with '+noredirect'. (Off course, XXX=MyAPIkey)

Thank you! :) Спасибо!
