One thing that I have been thinking about in relation to all these new streaming services coming out is that one thing that I am really keen on seeing is if the service will allow exporting of your listens, to last.fm for scrobling or just general export of listen analytics. I am hoping it is in the pipe line for Amazon & Google and whatever Apple delivers - however I am not holding my breath. I think google has the best shot of allowing the data captured out but for people like myself who really enjoying sending that info into other people's suggestion algos I hope with this new line of services I am not put in a box and forced to only use on the suggestion features of the provider (which usually only ends up being from record companies whom they have deals with). Don't fail me Google ;) !
