Compared to all the other games of the year the CDs Chartshow has (perhaps together with the Bravo) the best selection. And I provides a good recap of the Popjahr 2012. If you want to have all the hits from the Top 100, can buy individually yes for almost five times the price.
But with Carly Rae Jepsen, Michel Telo, Lykke Li, the Toten Hosen, Asaf Avidan, Psy, Alex Clare, etc. almost all number 1 title of the year are represented.
