Here again we see the greed factor at play, not content with getting airplay revenues, consumer sales, and all sorts of other revenues from sub-licencing an artists work these people want umpteen bites of the cherry and are looking to try to get more money from spotify a company who's shareholders are all recording industry companies, this seems like a long term plan to drive spotify into charging for music and for those who might have used them to feel sorry and chip in a few quid a week or somesuch thus increasing the revenues for the record companies.
They want to convert the spotify userbase back into hard cash paying customers in short and this public infighting is simply a mechanism to try to acheive this, what fun and games
Thers not much between youtube and spotify if your just listening is there folks.
