Steps to reproduce: open the auto tagger and clear all fields, then put something into album and/or artist fields that results in the error, e.g. as albums: "asdfg" or "Volksmusik Aktuell 2". Other search terms, like the album "Hard to Find Hits", result in a mixture of correct and weird results. Putting both artist + album may or may not change the results compared to only specifying one of them.
