For all you iPod lovers who had trouble with your song purchases off of iTunes (ie. Playing it anywhere else besides your iPod) you don't have to worry any longer.  Apple has decided that it's going to make all of its songs DRM-Free. 

DRM stands for Digital Rights Management which was enacted in attempt to alleviate illegal file-sharing.  DRM allows manufactures to control things such as how many copies of a song a customer can make, what devices the song can be played on, etc.   It was created in attempt to protect the rights of copyright owners, but has been very controversial because of the limited abilities it gives consumers.  The change in iPod has been anticipated as they are one of the last music companies to do so.

With the change to DRM-free also comes a price change.  Instead of the flat $.99 per song, prices will range from $.69 to $1.29, which will be decided by the record labels.  The songs will not be MP3s, but AAC format which usually has better quality than MP3s.  Price changes will not be put in effect until spring time, while iTunes is working now to make all content DRM-free.
