ps3 and folders (and a note on streaming)

[theknub]

hey guys,
so i have my ps3 up and running and am easily able to stream from winamp to the ps3. i use the remote play (based on orb) and it seems to be working great. so there other options than WiMP (note: haven't tried WiMP)

currently, my music library is set up something like c:\my music\artist\album\

if the song i have is by itself, it would just be c:\my music\artist\

basically, what i'd like one of two (both if possible). first, i wasn't able to do it, but can the ps3 read m3u playlists? if not, is there a playlist format it can read? second, can the ps3 parse through my entire collection and randomly shuffle through it?

pretty basic i guess, but my knowledge does not revolve around some of the finer points of ps3 usage.

thanks
