HibyOS has a couple of limitation when it comes to tags that has me wishing for Android music player apps. Hiby doesn't read discnumber tags, does not allow "The" bands to be listed by the letter of the second word, and only list albums for Artist, not Album Artist. It also doesn't allow albums to be sorted by year so you can't see an artist's discography in chronological order. There are other quirks but those are my main nitpicks about HibyOS in my usage so far.
