It doesn't matter where you're from. What you're asking for--a mobile music device with a touch screen and true drag-and-drop music management--is still a generation or two away from reality. However, there are players that feature a touch screen, which can be both an annoyance and a benefit to navigation and music management. The first one that comes to mind is Archos's PMA430. More of a miniature media computer than an MP3 player, this Wi-Fi-enabled device features an intuitive 3.5-inch touch-screen interface. It's expensive, though, and it's been available for more than a year. The Olympus M:robe also has a big touch screen, but it's not a good player, and it wouldn't give you the control over tracks you need. Actually, it's not even on the market anymore.

Another option is to get a Windows Mobile handheld, such as a Dell Axim, an HP iPaq, or a Palm Treo 700w. Although these are communications devices first, they run Windows Media Player, they're equipped with touch screens, and they have an inherent flexibility to run many types of applications. As for true MP3 players, I'd imagine Archos or Apple (with its rumored touch-screen device) coming out with what you're looking for first.
