... well, not in a software sense, but rather in a functional sense.
First, get a portable USB switch with manual on/off switches (not the autosensing variants) like this one @ $9.99:
Amazon.com : Sabrent 4 Port USB 2.0 Hub with Individual Power Switches and LEDs : Network Hubs : Computers & Accessories
Then, get 4 of these low-profile USB flash drives @ $9.99 per:
Amazon.com : SanDisk Cruzer Fit 16 GB USB Flash Drive SDCZ33-016G-B35 : Electronics
Some velcro dots to secure it to the console, and voila! You've got a slim, low-profile set of 4 banks of 2,500 songs that you can switch between on-the-fly. No fumbling multiple thumb drives. Separate alphabetically, by genre, whatever.
If you want more banks, Sabrent also makes a 7-port version, although attaching to the center console might be a bit clumsy:
Amazon.com : Sabrent 7 Port High Speed USB 2.0 Hub with Power Adapter And Individual Power Switches, Blue LED Indicator.(USB-H7PS) : Network Hubs : Electronics
The one downside is that the included USB cable ends up being a bit long and dangles. It might be worthwhile obtaining a short USB cable: note that it is uses a mini rather than micro USB connector at the switch end:
