Ok,
Seeing as your playing with version 9 and adding random features to it I thought I'd throw a few your way so you could possibly add them to it.
Also, I'd like to volunteer as a beta tester for it.
Could you add these fields:
Last Played date
Total Number of Times Played
Imported Date
Also the ability to edit the id3 tags of a song and save them without the song starting again from the beginning.
I'd also LOVE it if you'd make the import files feature smarter so it could detect covers for albums saved in a folder along with their covers.
Also (I know I mentioned it before but it's quite an important one to me so I'll just mention it quickly) the ability to filter the playlists by artists who have Less than or More than X songs to get rid of artists who only are in my collection by being in compilations or to filter in only artists with a half decent amount of songs.
The ability to browse explorer style my computer is now a huge bonus.
I'd also like a feature to export all my settings just from going to file - export settings, rather than having to do it manually and even then loosing all my registry settings.
I'd like the install program to be smarter so I didn't have to reselect all my file associations each time I install an updated version.
Smarter renaming rules so that I could for instance specify a format (artist - album - track # - track title) but then also specify alternative ones for tracks that missed specific fields.
File truncating when burning and file names are over 256 - I'd love to be able to have an option for these files instead of just having their names being cut short, have their names instead re-created from the id3 tags using formats of my choice.
Ability to have Media Jukebox span playlists over multiple cd's for burning.
Make it prompt weather or not to empty the playlist after a cd is burnt.
cant think of anything else right now
Oh yeah,
for your sake more than mine,
I HUGELY recommend making it support the PC iPOD as this would be something you could then use to make Apple advertise your program which would give you a LOT of business.
