It looks like Nokia’s unlimited music download service (that was available on specific phone models) is going to be discontinued this year. It is being discontinued as we speak in Finland, where the news come from: no new Comes With Music / Music Unlimited handsets are shipped to Finland after 12/31/2010 and the 1 year licence can not be renewed after 1/10/2011.
This probably means that the service will be discontinued in most markets in 2011 as well. The service could survive in some special markets, like India. There is no official announcements from Nokia yet.
Nokia’s usual Music Store (where you can purchase songs one by one) continues to operate.
One can only guess why the service is being discontinued. It probably didn’t gather enough interest and drive enough handset sales.
