Its only a matter of time when CDs may become what vinyl is today to some. Not referring to the warm analogue sound quality, but the minority in titles released in that format.
Soundbuzz and ;Play has been in SG since 2003 or earlier. I think they work with Pacnet and Starhub so you can pay for your songs through your internet bills or something. No credit cards involved. I will start buying from them only if they fix their idiotic user interface (try doing a song search yourself) and the forgettable catalogue they offer.
The illegal P2P sharing boom period is expected to die down soon, due to ongoing developments around the world where legislators and the industry are evaluating systems on how to make music (and other digital entertainment) truly affordable and widely available (even obscure titles), while fairly compensating the musicians and artists behind the song.
Most likely, we may soon see some form of compulsory low monthly subscription "fee"(tariff) which will be billed through the ISPs (like Pacnet, Singnet), and eventual legalising of P2P sharing.
Meaning for example every internet connection owner will pay additional $2-5 per month. You are allowed to share till the cows come home. Systems will implemented in all P2P software to trace which songs have been shared in a particular region and how many times the song was copied. The tariff $ collected from the ISPs will be distributed to the rights owners (songwriters, performers etc) based on how many copies of their songs were downloaded.
Far fetched as it may sound to you, but it may happen very soon. They call it the "music like water" concept. Everybody uses it, everybody pays for it, just like a utility bill. This way the cost/consumer is spread out and yet the total amount collected and distributed to the rightful owners is many times more than what it is today (by selling CDs).
Those of you who are interested can go to Esplanade library reference section to read a 2005 book called "The Future of Music".
