My idea about requirements somehow like Jun but lower in the number:

10 songs together / 3 songs & 1 CD / 2 CDs.

I don't know much about YT singers but utaite, up to now, i believe UraSaka is the duet unit with largest number of duet covers and it's just around 12-13 songs through 4 years. Hence, 20 covers is, somehow, like 'mission impossible'.

Form of this page only need to be the same with group page, cause actually, duet unit is the group with 2 singers.

I totally agree with Jun's last idea ^_^
