This might be pilot error, might be bug report, or I believe most probably a feature request.
To explain: I keep my albums organized in a 4-tier hierarchical level. That is:
top level: Rock, Classical, Jazz, one folder for each genre. (Tags don't always carry the genre, so that's how I keep them sorted.)
second level: Folders by artists. So the "rock" folder could contain the Eagles, The Beach Boys, etc.
The Classical Folder splits them by composer--which again has to be done manually as these days, the albums tend to be titled/authored by orchestras and other choices, not "Beethoven" or "Brahms".
third level: The album folders themselves. So, for each folder on the second level, there may be a dozen sub-folders, each with one album in it.
OK? Simple, logical folder organization?
But Poweramp does not think so. If I ask Poweramp to shoe me my library by "Folder", it only shows me EVERY THIRD LEVEL FOLDER, all commingled. I can't say "Show me all the rock folders" or show me all the Polka folders. (Just kidding, no polka music here.) The only way that I can tell Poweramp "Show me all the Jazz folders and random play from that list" is if I either go into the setup and select ONLY that top-level Jazz folder as a music source, or if I go into the playlists after doing that, and compile a new playlist--which has to be done again every time I add a new album folder.
Shouldn't there be a way to bring up the library, select FOLDERS, and have Poweramp recognize that their are tiers to the folders? Select from top-tier folders the first time, DRILL DOWN to select from second tier folders under one or more of those, and DRILL DOWN again if I want to get to the artist level folders?
This is almost as frustrating as my car music player, which only knows how to do random tracks from "ENTIRE MEDIA?" rather than from a subfolder on that.
And I'd be delighted to find out if this is just pilot error, and the latest v.3 Poweramp really does have some unintuitive way to accomplish this. REALLY delighted!
Still my top choice in music players.
