[AC Question]

I keep my music on my SD card. The problem I have is with my music. I keep it organized, putting in track list numbers manually. With Lollipop 5.0, my phone reads all of the songs' track list number as 0, putting them in alphabetical order. Interestingly, when I put a new album on my phone, it reads the track list numbers normally, and puts the songs in the order they are on the album.

Welcome to Android Central! How are you editing the tracks? Are you editing the actual ID3 tags? That's how the system is looking for the track numbers. If those are tracks you downloaded individually, perhaps their ID3 tags don't have any track information, and the system is reading each of them as Track 0 by default. Use any ID3 tag editor (either for your computer or for Android) to edit that information.

OP here. I am editing the actual ID3 tags. The problem is specific, I have discovered, to files in WMA format, which is the format most physical CDs use.
I've been messing with ID3 tag editors all morning, to no avail. I also used a file converter to put music into an mp3 format, but they won't transfer over to my phone again for whatever reason.

It's been a while since I dealt with WMA, but from what I remember, they can cause some funny business with Android. I wasn't aware that physical CDs used WMA. I usually rip the tracks as either MP3 or AAC.

I actually got it to work. I used a different converter, and just finished putting all my WMA files into mp3. They work fine now. Thank you very much!

Good! So are you saying you converted your WMA to MP3, then edited the MP3's ID3 tags? Or did you edit the ID3 tags in the WMA file, then covert it to MP3, and then it worked?
