What about the software dont you like?
1. Doesn't have an Album Artist category.
2. External playlists (i.e. not created by Pioneer's player) are listed but they're empty.
3. Genre category doesn't group by Album Artist.
4. UI is untidy and messy (e.g. too much white space between lines, can't get rid of background image, text overlaid onto album thumbnails, nothing is "delineated" - I think this is Material View not done very well); UI is also a bit awkward and unintuitive, too many swipes to remember.
5. Compilation albums that are listed in the Compilations tab are not removed from the Artist tab (this exacerbates the Album Artist problem).
5. Albums are sorted alphabetically within artist, not chronologically by year.
6. Bluetooth seeking (long press on Next and Previous buttons) doesn't work.
7. Would be nice to have smart/dynamic playlists like GoneMad has.
I think there were a couple of other things too but I can't remember off-hand, I sent them all to Pioneer months ago, but after the first one or two software releases it looks like software development and bug fixes has stopped. The last release was 6 months ago?
[EDIT: I forgot, there was an update about 2 months ago I think but it didn't change a great deal. Aquare album artowrk added to Now Playing, Seek possible using the hardware Next and Previous buttons, but nothing else visible I think. Comments from other people on the app in the Play Store from months ago also point out the UI issues, Album Artist problem, and albums not sorting by Year.]
