While trying this I found a potential licensing problem in the code -- it links statically with some random RealNetworks MP3 decoding library, thus the entire program falls under the RPSL, which is GPL-incompatible; but there are some GPL components statically linked too. I personally won't pursue it (since it's one of those stupid legalese "only in name" changes issue), but I also have to wonder why to use the Real MP3 library...
