There was an interesting article in Dagens Industri today (online but subscription requierd) about ABBA, the Swedish music group. On Wednesday the band will launch an online music store on its website where they will sell ABBA songs directly to fans. One of the smart features of the music store is that fans will be able to embed it on their blogs or Facebook profiles, literally creating tens of thousands of ABBA stores online.With the store, created by the Swedish company Dimest, the band will be able to keep as much as 90 percent of the revenues from the sale. The songs will be sold as mp3 files in higher quality than Itunes and without copyright protection.
