Art, any on-line download site is going to have DRM in some form on their purchases. iPod users are faced with the same problem with songs purchased somewhere else besides iTunes, you can't get them on iPod because of the protection. It's basically a 2 way street, when you say it doesn't serve Apple well. How about the major record company's choosing to lock out the dominant portable music player on the market using protected WMA format?
There is a way around this if you or your daughter want to invest the time & the blank CD's, burn the purchases to an audio CD, use the audio CD to re-import as mp3. Now, the purchases are in mp3 format & should be transferable. Hope this helps. Happy New Year!
