Latest daily ranking: 17th (Saturday)
Third week progression:
9, 14, 23, 27, 25, 26, 17
With only Sunday's ranking to come a weekly top 30 ranking seems to have been secured.
These rankings are quite impressive. We have to go quite a way back in time to find a HP single that's doing as well as Balalaika in its third week (ranking wise).
In early 2004 Momusu's Ai Araba was 29th in its 3rd week and if before that in November '03 Go Girl was 19th in its 3rd week.
