This strikes me as a cool idea (it sounds a lot like Open Sky, with no purchasing) - but what frustrates me is that my attention span for music these days is such that I would probably listen to something featured on this site for like 2 or 3 days and then totally lose track of it in the overwhelming surge of music that is available these days.
There are like maybe two albums from 2011 that I can sing all the way through. I used to buy a CD and wear it out.
Sounds like you need to find something you love and focus. Everyone once in a while I get stuck in listening to new bands, because there are so many great free releases out there, I gotta force myself to relisten to some stuff I was really feeling and actually get very into it.
