At the very least, if you're playing DRM media
So that means if you are playing from a system
which is not online (say your notebook while you
travel), you are basically doomed, and can not play
the music you paid for?
I don't generally listen to music (at least not
by choice), so I don't know much about the details.
Probably you'd need to confer with someone using
the same service.
My impression is that each DRM system varies,
but that most or all do online "license checks".
There's at least one service where you pay monthly
and all your songs stop working if you quit the
service. That must require a regular online
contact as well. On the other hand, it's my impression
that Apple allows a limited number of CD recordings.
I can't imagine how they keep track of that.
I'm actually very curious about what most music
fans are doing. Downloading "illegally" seems like
risky business for adults to be getting into, but if
it were me I can't imagine paying for a crippled
recording, at virtually no cost to the record company,
but at about the same price that it would cost buying
a CD. I'm amazed that people are paying $1 per
song for DRM music. I suppose the product in
that case is really convenience more than anything,
since people could easily copy each other's CDs
and record from the radio for free.
