Ok, I'll keep it in mind. Frankly, M0 is too small for my taste (I think M1 is the perfect compromise between portable and a nice screen).
Once my M1 is due for replacement, if there's a new player with similar screen size but your own software and features, then it's a no-brainer.
For now I will solve my problem by creating Artist playlists. Folder navigation is good and avoids the file limit entirely, I'm having no problems.
I've written a bash script, which runs in Cygwin (Linux command line environment on Windows), that will find Tracks with a specific Artist, by searching the Tags that I've set in JRiver Media Center (when ripping my CDs). The script returns the information in a format that can be redirected into a file, to become a .m3u Playlist.
