Brother to Integrate to Telcos can set you back about 1 Year +, to get VAS License from NCC that one na you and God know when it will come out, then you pay for fees, then pitch your product to the Telcos to add you on the list, then doing testing to see if your core system is compatible and then marketing blast( you would have to clean your database, MTN and others wont do it for you), geo-targeting, building your VAS System sets you another 1 year, the big boys in VAS arent using CRBTs anymore but doing Campaigns for Brands to stay alive, so i wont advice you think because some people by Ring back tunes you should go that route.
Best thing i think we can try is to see if we can restrict codecs or encrypt them so you can only listen to a song, you cant share, you cant download, you cant copy because it links to your device only( till the tech comes) OR a thorough clamp down on free music sites or blogs( impossible)
Best thing they can hope for is the changing dynamics of the country via broadband penetration growth and other factors like rising middle class and hence are creating Strategy for the future where younger generations will prefer to stream than download and Maybe pay a little to do so.
Alternatively, Music sites that make us download songs can be enforced that for every download they pay royalty to Artiste( be it 50 kobo or so, maybe when guys begin losing money they will push for Streaming instead)
But for now...Nothing new
