CNet has revealed that researchers at the University Robert Morris last November, said the test tracks play an important role in the process of purchasing a user. In addition, in a report released by the university in 2009, said Professor and Assistant Professor Min Lu Yanbin Tu, consumers are more likely to buy songs if they were allowed to listen to music samples of about 60 seconds.
At the beginning of last month, Apple said that the change will occur 90 seconds of a song that has at least two and a half minutes long. Apple also provided confirmation to continue to provide the sample of 30 seconds of the song is shorter than two and a half minutes. Mac maker is already declared record companies and other partners in the music industry change. Thus, it is hoped that this message will not be led to protests from the party label, but do it as an advantage in offering music to the listener.
