I use the Zune software on my PC instead of WMP11 to stream mp3's to my 360, mainly because WMP11 always gives me trouble with updating my library of songs. Anyway everything works great as far as the streaming is concerned (other than it doesn't have gapless playback) except the 360 doesnt correctly read the disc number tags in the files! So if i have a multidisc album it plays all the track 1's first then the track 2's, etc. I have about 35000 songs and i have them just the way i like them (i.e 'The Wall' is one album with a disc 1 and a disc 2 set with the id3 disc# tag as opposed to having 2 separate albums 'The Wall Disc 1' and 'The Wall Disc 2') and im not about to go back and change track#'s either. Ive given up on Microsoft ever adding support for this, does anyone have any insight into potentially adding support for this via modification of the Zune Software System Files? Or is it how the Xbox 360 interprets that data and in order to add this feature it would have to be console side? I know nothing about programming and was hoping someone could give me some insight!
