You can move the files to the SD card. Google does a good job of hiding them deep in an inconspicuous folder, but they're there. However, once there they've given all the track files a random number for names with no other identifiers on them, so unless you do it one or two albums at a time, good luck trying to figure out the artist, track, and album names from 2,467 files that are in no particular order. It would take six months just to re-label a 100-album collection. Maybe you've got that kind of time, but I'll just pay the $9.99/month to listen whenever I want. When you consider that most of us used to pay $15 for an 8-12 track CD and before that, $8.99 for a terrible platform in analogue tapes, it's not exactly a bad deal for unlimited downloads of 320Kps music of all kinds in perpetuity. Sometimes I wish I could pull some of them out for mixing purposes, but rather than essentially steal royalties from artists I respect, I'll go buy the tracks from Juno or Beatport. Call me a boy scout if you must, but I'm a musician myself and I respect the artform, nevermind how much more difficult it is to make a decent living doing it these days.
