Step 1Introduction to the VMUSIC2 module
The VMUSIC2 module is based on the Vinculum VNC1L USB Host controller from FTDI and the VS1003 MP3 encoder/decoder from VLSI. The VMUSIC2 allows you to plug in a USB flash drive filled with MP3s and play them from your microcontroller.
This module is inexpensive and comes in an enclosure that can easily be mounted in a panel cutout to give a professional look to you project.
The main advantage to using this module is that it only requires a few pins to control it, and the software overhead is very small. This allows your microcontroller to focus on the rest of your project (monitoring switches, etc...) while the MP3 is playing. It also means you can get away with using microcontrollers with less program memory and fewer I/O. Another advantage is that you don't need to know anything about programming for FAT32, USB host, or MP3s.
While the VMUSIC2 module is designed for playing back MP3s, the USB host interface can also be used to access (both read and write) any files on the flash drive. When I get to the instructable where I connect this to a microcontroller, it will be apparent how useful this is.
You are going to need the following items to complete this instructable:
*VMUSIC2 Module from FTDI.
*RS232 to RS232-TTL-3.3v converter (if you connect this module directly to your PC serial port, you risk damaging it. See step 3 for a suggestion)
*5V power supply
*A computer with hyperterminal (included with windows) or some other terminal program
Got everything? Good let's take a look at the module:

I am wondering does it have a delay when changing songs, or it does it rapidly?

I don't remember there being an unusually long delay. It isn't immediate, if that is what you mean. I don't have one connected up at the moment to check this for you, but a delay didn't seem noticeable to me at all.
