if similar to WIL (song), i think it can go top15 at least. Top10 is very very competitive right now im not sure how well Twice can compete
If similar to ICSM / CFM, i think forget it. They will chart top30 until promo comes in
Album will sell in the range of 300k to 400k
nah the album will definetly be over 500k, they have a month of pre order and a lot of links. they broke some of their pre order records already.
