Diskussionen → phplastfmapi and Autocorrect not working

How can I get the autocorrect param to work correctly? I am using the phplastfmapi Library. I modified one of the examples and just changed around a couple of characters to test the autocorrect and it is not working. This is in the track.getsimilar directory:

$methodVars = array(
'artist' => 'Adel',
'track' => 'rollin in the deep',
'autocorrect' => true
);
The artist name and the track name need to be spelled exactly correctly to yield results. I am getting my input from an unreliable source so I need to account for autocorrect. If lastFM API doesn't take care of this, any suggestions on using another music library to correct the incorrect output? Thanks!

Only when I type the artist and track name correctly does it not return to me: "Error 90 - This track has no similar tracks"

The autocorrection feature is for most common naming mistakes, like with Guns 'N Roses (correct: Guns N' Roses) not for typos :)
Because there might be a different artist/track with exactly this name :) On the website it will show you a "Did you mean Guns N' Roses" text on a yellow background above the artist page content.
