I got in touch with a very helpfull representative of VLSI solutions, who was good enough to send me some VS1053B chips. I also ordered the sparkfun musical instrument shield that has this same chip nicely broken out. This means that it can be a standalone device of people want. This is very important to me - I am hoping to find a company willing to sponsor the manufacture of some of these to go into schools and homes here in Zimbabwe, where hopefully they will let people who have never played music before experiance something new. I will upload all the code and a video some time tomorrow, once everything is polished. The sound quality of the VS1053 isn't brilliant but definitely good enough for everything I have in mind, and it only costs around $5 in reasonable quantity which, condidering that it negates the need for serial USB or bluetooth, isn't bad.
