Price of download single (3-4 minutes high quality music): $0.99.
Price of downloaded ringtone (30 seconds radio quality): $4.00.
Why? Because phone manufacturers don't allow mobile phones to play MP3 ringtones. Why not? Because they also profit from the ringtone business (Nokia sells ringtones and logos in Europe).
The music industry already makes more from ringtones than singles...
Hence I present you with the next greatest concept in consumer-from-business theft... RINGTONE PIRACY!! Yes, 12-year olds will be hauled before the judge for illegally swapping ringtones. Modchips that allow mobile phones to play "illegal" MP3 songs (But, yer 'onor, I own the CD!) will be banned in all civilized nations.
Just wait for the Slashdot headline "Ringtone pirates sentenced to 12 months".
Or don't. You read it first here.
