One way to start a new year is to look back on the year that just ended - if there is something worth to remember...
As on previous years a listing of the biggest hits of 2011 on The Official Finnish Singles Chart has been published on Listablogi. That list is based on a point system based on the songs chart positions and weeks on chart and is the closest one can get to a complete list of biggest hits of the year in Finland, as Musiikkituottajat – IFPI Finland only publish lists of best selling songs and singles based on their certifications. Those lists are separated into Finnish releases and Foreign releases, but the lists haven't been updated for several months.
Aided by the Finnish World Championship in ice-hockey Poju's Poika (saunoo) was the biggest hit of the year, although the #2 on the list Petri Nygård feat Lord Est with Selvä päivä was released already in 2010 and would've topped the list with its complete chart run. Adele with Rolling in the Deep, Haloo Helsinki with Maailman toisella puolen and Jennifer Lopez feat Pitbull with On the Floor rounds up the Top 5. Adele is also at #8 with Set Fire to the Rain and the current number-one single in Finland Someone Like You is at #36 on this list. 2010's biggest hit, Jenni Vartiainen's Missä muruseni on, is #26 on 2011's list, and according to IFPI's not very recently updated site it is the biggest selling single of the year with sales of 8 824 in 2011.
It's worth to mention that songs with huge sales week, such as Nightwish's Storytime (#45), would be higher if it was a purely sales based list. 38 out of 100 songs on the chart are Finnish/domestic releases. The complete list of 2011's Top 100 Singles in Finland can be found here
As sidenote it can be mentioned that Jenni Vartiainen's Duran Duran (#10 in 2010's list, #47 in 2011's list) was the most played song on Finnish radio in 2011.
