Hey, thanks for the report.
Unfortunately, I wasn't able to reproduce this either; everything was Beethoven for me.
Please let us know if you find any other search terms that return completely unrelated results. I’ve mentioned this bug internally, but I’m not sure how much the team can do since it seems to be isolated to your account. Needless to say, this shouldn’t be happening, so hopefully a solution is found soon. I also hope the issue doesn’t affect your other queries.
