To unlock the iTune's DRM

More and more people including me seem to change the way to enjoy music. It has become more popular to download music instead of purchasing CDs. Actually I have not bought any music CDs for more than two years. The more people shift to this style, the less sales of CDs cannot be avoided.  I don't know whether it is good or bad, but I can say it is the trend. The combination of iTunes, iPod and its music store is the most successful service around music in the past several years. I was surprised to find that I have purchased more than 200 songs from the music store. One problem of this service is that the songs are all copy-protected and we can't copy them without limitations. I don't intend to make illegal copies but this limitation had been an unpleasant and stressful thing for me until I unlocked them yesterday. If you have some song files with DRM(Digital Rights Management) and you are feeling unpleasant, QTFairUse6 will let you happier. All I had to do was executing the unlocking program on the PC with iTunes and waiting for thirty or more minutes before all the protected files were converted into unlocked files.
