Not sure if you've tried it out yet - I for one don't care for it!
It does work, so that's a plus. But it doesn't act at all like opening just another window or drive. On my hard drive for example, I have a folder for every artist. Within them, I have folders by album. Within that are the songs on that album. But when I view the Riot contents via WinXP, I just see song names. Tons and tons of song names. It appears the Riot categorizes using the ID3 tags, so that's a bonus. But if you were to say choose to delete an album using this powertoy - all you could do is find each song one by one and attempt to remove them.
In short, nothing like "just another window", nothing like the emplode either.
Guess I'll try the bundled Real software, oh joy!
