Well it could be considered if there's way too many of them, as YT singers tend to duet much more (and much more easily) than Utaite to my memory Sen 01:59, June 26, 2012 (UTC)
aa, i see... (i don't know too much about YT-utaite). well i removed several "uptodate"-templates from YT-utaite-pages, in the past, due to missing duets...BLUEBIRD 12:46, June 26, 2012 (UTC)
Well the thing is they also have "duet ready" covers they do (more info here) so its possible not all the ones you're finding may be "official" Sen 18:34, June 26, 2012 (UTC)
