Yeah, in comparison:
First day sales - First week sales
DTF: 20,233 - 38,999
Mamore: 41,815 - 56,232
So I reckon the estimated weekly sales for One Up will be around 45K.
If I'm honest I'm not really feeling this single. It's like "they" studied which elements lead to good sales: bikini covers, sexy PV, decent promotion, etc. and they put it all in this single. However, I feel none of it really matches. It doesn't feel like one well though-out concept. The song is pretty weak and it doesn't really go with the PV. I really want them to do well, but I feel this has been a big missed opportunity. If you're gonna go all out, make sure they get an epic song as well.
