The name may sound like something out of a Final Fantasy game, but we hear it stands for Music On the Go, and today MO is doing the name proud by bringing a wide swath of streaming music to Android and iPhone. $10 a month gives you access to 7.8 million songs, and during a completely unscientific impromptu testing session, that number actually included a reasonable amount of most everything we'd want. Of course, you don't get to keep any of the 320Kbps MP3 files, merely store local copies on your phone for as long as you pony up, and even on Android (where we take task switching for granted) the merest jump to web browser stops those tracks cold. (MOG says it's working on it, at least for the iOS 4 version.) We were also disappointed to find out the MOG Radio feature is nothing like we were told -- rather than a Pandora you can tune to specific artists, the feature just seems to filter your existing queue. Playback options were also lacking in this early version (like volume and jog sliders) but at least MOG's got a slick, robust discovery mode, and with this many songs to choose from that's a very good thing. Both versions should be live immediately with three-day, no commitment trials, and there's a press release after the break if you still need more info.
