I am pretty dure you can enable the psp to play wma now but you would have to check at
http://www.us.playstation.com to be sure
If so then basically evey single service it seems except i-tunes will work
Yahoo, Virgin digital, rhapsody,msn music, and yes Napster to name just a few.
And of course if you actually purchase the wma's form any of them there are tons of software that will then convert the wmas to mp3 that always worked there.
