This is going to sound dumb, but I recently bought the Fiio FX1221 without knowing much about it, on a whim I guess, and don't know what to do or where to go to get music. I am used to the iPhone and iTunes, have bought quite a bit but don't think that'll be able to download to the new unit. Can someone point to a download source where I can get some tunes for free? My tastes tend to be old rock and newer country, so I don't need the latest pop or metal. Thanks to anyone that can offer some help.
