Online music bubble to burst by year end

'Since the launch of iTunes Music Store last Summer, online music stores have been springing up all over the place. Soon, consumers will be able to choose from upwards of 50 download sites for their digital music needs. According to Forrester Research, it will be all downhill from there, as by the end of the year many of them will be out of business. ... Forrester predicts the demise of the CD in the next three to five years as they join 8-track tapes, vinyl, and cassette tapes in boxes down in the basement. ... Chances are CDs will be around for longer than Forrester predicts, but the changes in the music industry have begun and are irreversable at this point. Who besides Apple and Microsoft will be left standing when the bubble pops?' Ars technica
