Music Transformer is a software for Mac OS X that helps convert iTunes M4P music tracks to different formats including MP3, AAC, AIFF, WAV, and Apple Lossless. It doesn't alter the original iTunes files and can be used with virtual CD software or a CD-RW.

The purpose of Music Transformer is to convert iTunes M4P to one of the formats that your device can play. It doesn't change the original iTunes M4P file in any way, and the software works with a CD-RW or Virtual CD software to do the job.
Setting up iTunes for importing and launching Music Transformer is a breeze. Once done, you can select the playlist you want to convert, choose the format you want to convert from (M4P), and the format you want to convert to (MP3, AAC, AIFF, WAV, or Apple Lossless) before clicking the transform button. The software will then take care of the rest with the help of either a rewriteable CD-RW or Virtual CD Drive software.
When deciding whether to use a rewriteable CD-RW or Virtual CD Drive software, it's essential to consider the cost of your time. CD-RWs are affordable and convenient, but if you're converting many iTunes M4Ps, it can take a while to complete. On the other hand, using Virtual CD software is approximately ten times faster than using a CD-RW, making it the faster option.
Overall, Music Transformer is a must-have software for Mac OS X users looking to convert their iTunes M4P music tracks seamlessly. It's easy to use, fast, and gets the job done without changing the original iTunes file.
