Now call me old-fashioned, but piped music on the bus (or anywhere else for that matter) is not what I'd want.

I've stopped going to my local Asda and now travel much further to Sainsbury's, mainly so I can shop in relative quiet. The local Asda is half way to being a disco. And I find it difficult (and somewhat inelegant!) to boogie on down while holding a bunch of spring onions!

I know bugger all about the technology of it, but I was under the impression that railway carriages could be "lined" in some way so that mobile phone signals can't penetrate. I'm not sure that all railway companies have quiet carriages. I know that South West trains have them (and they enforce the rules - good for them!), but I'm not aware of any on Southeastern.
