Results by language in iTunes and iTunes Radio?

Is there any way to filter iTunes Store results by language? It seems excruciatingly difficult to browse artists in any language other than English. I understand that tracks sung in English probably sell much better and therefore come up more frequently as suggestions, but is there a way to filter results to show best sellers specifically in another language without switching to a different country's iTunes Store and then back?

Also, is it me or is iTunes Radio completely oblivious to language as well? If I create an iTunes Radio station based on a song or an artist in another language, it plays exclusively English tracks, and often gets confused by the station and starts playing things like tracks from a Batman soundtrack. Is there an option somewhere that I am missing? On the bright side, stations based on English tracks or artists work perfectly.
