single: Days / GREEN - SALES (?)

[SURREAL__RAINBOW]

I just want you guys to guess how many copies this single is going to sell...
GREEN is a good song, but I really didn't like the pv that much, I think it could've been way better. Days is a pretty winter ballad, but is it strong enough to give to this new single good sales?? I really hope that this single gets to top 1, for one week or more at least.


I guess that this single may sell less than 100.000 in the first week, what do you guys think? more? less? top 1, 2, 3?? thanks for commenting!
