Even in densely-populated European countries, 3G network coverage isn't anywhere near good enough to allow this sort of thing.
FM (and DAB) radio will be around for a very long time - they're simply the most efficient way of delivering music and radio programming to large numbers of people across a wide area.
It works for you now because about three people and a dog are doing it, but if even a fraction of the audience of an average regional FM radio station started to stream their personal Pandora / Last.fm accounts or listen to on-demand programming over the 3G network instead, it would very quickly reach capacity.
Well Verizon and AT&T now own the spectrum that was once used for analog TV. LTE should be able to sustain and provide the level of bandwidth needed for this.
A Clear channel or iBiquity (HD radio which is boring and needs a Pandora to jump start it) could be potential buyers of Pandora. I would say those who invested are looking at such entities as potential buyers. Also, another potential reason why Pandora is jumping onto RIAA ship saying clear channel should pay the same rates.
It may not be feasible now with 3G, but 4G and other future wireless options will be.
A large number of people can all use their cellphones at the same time in a fairly small area. High quality personal radio might take more bandwidth, but it's one directional and most cell towers cover a small area. Honestly, I don't think it would be much of an issue to build that much extra infrastructure.
