Hi, i have an mp3 player in my car and was thinking of a way to jump though my music with a bit more ease, atm i have a USB loaded with lots of music files but would like the freedom of jumping between playlists. since the stereo only has one usb port, the idea is a circuit that can dismount and mount USB drives and move to the next though a single button press. kind of like those old multiple CD systems that would cycle though physical disks. any ideas on how to achieve this?

would i just have to have the switching happen between the data+ and - for a 'NEW' drive to be discovered and mounted by the system?

Possible, but if you switch data + and - and power also it would help eliminate the possibility of the USB getting hung or not resetting properly. Maybe a small three pole relay? The ground could stay connected.
