I just added an Earth, Wind & Fire song to my library. AS properly got the MusicBrainz ID and then got images, bio, and similar artists with no problem. I would need to see a log file to help further.

First off, Thanks pkscuot for creating a great addon for xbmc and all your hard work.
It was a bit of a battle getting this addon for me working correctly, but with 1.6.2.6 installed it now runs 99% correctly.
sveni_lee and I have a similar problem (don't know if it's exactly the same, but here goes)

I can now get artist information, concert information etc. for every artist except ones with a comma in the artist name (example - Crosby, Stills & Nash)
I have used artist slideshow helper to fix certain artist in the past, but even when AS Helper tells me the name of the directory for say - Crosby, Stills & Nash it doesn't exist.

So I've found for me that any artist name with a comma in it, AS does nothing. It just seems to sit there, it doesn't even create the directory where the information would have gone. If I remove the comma from the artist name to say (Crosby Stills & Nash) it doesn't have a problem finding the artist.

Here is the log file. Hope this helps - http://pastebin.com/WXNVugFg
