1 - The whole deal with the "social music revolution" is a crap. They simply used users scrobbling and voluntary efforts (editing info about bands) to systematize and develop radio stations.
2 - Suddenly there is the decision to charge a fee for the service, except for US, Germany and UK, "social music revolution"? Typical hypocrites, people earning cash with this enterprise are themselves are prolly Brits, Germans and Yankees that care about their huge tax duties.
3 - Marketing in the internet that you offer free music and than charge a fee afterwards goes against consumer rights (at least where I come from there is the right of not being fooled through marketing tools. Btw, a place where consumers receive decent legal cover).
4 - Even though I wouldnt need to pay this situation really pissed me off. So I deleted my account and by the way I discovered that I does not erase a bunch of posts and entries that still happen to be at google searches.
5 - They list your nickname, songs and forward you musical taste for commercial purposes to other websites...I did not read the fine prints...and wont.
6 - There are other options that provide the same services for free.
