Your investment in CDs has paid all kinds of dividends over time because third parties could freely enable novel uses, like ripping MP3s or creating your own ringtones. But when you buy DRM-crippled music, you're locked into the limited array of software and devices that DRM vendors say you can use.

Many online music stores offer songs wrapped in Microsoft's Windows Media Audio (WMA) DRM, but not every device supports this format. But what happens if you later want to switch to a WMA-incompatible iPod, or a superior device that Microsoft won't license? You'll have to rebuy your music collection. Unlike MP3s, you can't easily convert DRM-crippled music to a different format.

If you use any of the itunes store to buy music downloads, you might be pretty unhappy with the limited amount of things you can do with it.

MAC M4P Converter M4P to MP3 Converter does not crack the protection; it simply burns music to a Virtual CD-RW disc and then automatically rip/encode the music stored on the Virtual CD-R. In this way, MAC M4P Converter can convert any formats of music to any formats. Because of the method it uses to provide you with unrestricted files, its use will be completely legal in most countries.
