The music industry hasn't figured out yet that punishing your legitimate
customers makes piracy okay in most reasonable people's minds (if it wasn't
already). Or rather, Sony hasn't figured it out yet, since Apple and
Amazon have gotten over themselves and they're a lot more successful at
selling music online than Sony has ever been.

When they say "the file might be DRM-protected", they mean the file is
encrypted and the keys to the encryption are in the phone. Sony's phones
and format are nowhere near popular enough for attacks on the encryption to
be successful, so your best bet is to get a patch cable and record the
phone's output into Audacity or something, and then export that as an mp3.
