What is currently known is that 11 new mp3s can be added without interferring with any already existing mp3s. After that we can overwrite existing mp3s with new ones.

However while I was writing this I was inspired by the method OSI used to add new mp3s and it might be possible to add an unlimited number of them. Soon as I'm done ripping UO:ML assets and reinstall UO:Gold with Nightscape I'll investigate this further. More details to come.

While not important, the origin of these are questionable. The names of the songs, match those of monsters included with UO:ML, so not sure...

The maximum bitrate for a song used with UO is 64kbs. This does not imply a song encoded higher than this cannot be used, it simply means that anything higher than 64kbs is dicarded by the client and equates to wasted bandwidth/memory.

Several of the optional songs listed above are encoded much higher than 64kbs and this is simply a test to see how well the software I has can re-encode the mp3s to a smaller bitrate.

320kbs (original)	64kbs (re-encoded)
