I have a ton of MP3 and WMA music files on my dinc's 16GB SD card, and they worked equally well when I had Android 2.1. After downloading Froyo, my phone forgot the artist names and song numbers and cover art for all the WMA files, but not the MP3 files - MP3's are still 100% fine. When I go into the Music widget (either the HTC or Android one), all of the WMA songs say "Unknown Artist". The album names are still correct, but it also forgot the song numbers for the WMA albums so they play in alphabetical order instead of the correct song number order. Aside from ripping dozens and dozens of old CD's over again in MP3 rather than WMA format, what could I do to make my phone remember all the artist names and song order and cover art for the WMA files again? I've tried unmounting/remounting the SD card and restarting the phone.
