When I buy music on e-shops, like JunoDownload, they usually provide ISRCs in files' metadata. However, for some reason, e-shops usually (though, not always) separate values of ISRC with hyphens. For example: "GB-XWZ-08-00015" instead of "GBXWZ0800015", so I think it would be great, if MB automatically cut it out, when user pastes ISRC in the field (in the same way as normalization of the links works on the "Add URL Relationship" page).
