Legally downloaded music all have DRM restrictions built in which limits what you can do with the file. Different companies use different types of DRM but the standard restrictions normally limit you to using media players/devices from the same company or only the ones you downloaded them through. For example Itunes mp4's will only play and burn through Itunes, Sony's AAC's only work on their players, and .wma's will generally only work through windows media player or the player you had at the time of download.
The only way of making them usable to all is to create individual audio CD's through their own linked media player then to rip these audio CD's back to mp3's. Mp3's are playable by all and have no inbuilt DRM.
DRM is there to stop file sharing so you should still only use those mp3's for your own personal use.
Whether you can actually be bothered doing all that is another thing and is what companies count on to limit file sharing.
