Computers might sometimes be faster and sometimes be slower, depending on the temperature, how fragmented the data is etc. If you kept trying and made a statistic, you might get another result; logically, a music program that uses some of the capacity of the computer for playing sound can only slow it down, if it doesn't have a built in program that does something and speeds the computer up somehow by... I don't know. But now I've got my daily logical thinking time, thanks for something to think about.
