UPDATE (09/07/2008):

1. PocketMind's Pocket Music (starting with version 4) is also able to use a full library via Menu / Playlist Organizer:

There, it allows for quick export to the current playlist (which can also be saved to the file system). That way, it only takes some taps to quickly start playing a library selection (select the files you'd like to listen to, tap the rightmost icon at the bottom (with the folder and the arrow), switch to the Curr. Playlist tab and, there, click the leftmost, playback icon. Note that, in this tab, you can also make mass selections using the righmost two icons (checkbox and list):

You'll want to use these before adding to a playlist that already has some elements and you'd want to easily (to avoid having to check in their checkboxes one by one after the addition) delete them before adding the new songs.

Unfortunately, Pocket Music (as opposed to ALL the other, reviewed apps), as of the current, 5.1 version, in no way allows for saving the library info anywhere. This means it'll always rescan your library upon invoking Menu / Playlist Organizer if you, in the meantime, restart the player:

This can be pretty annoying, particularly if you don't want to create playlists but want to dynamically, based on the library, select what you would like to listen to. Also, reading the library isn't very fast either: reading all the metatags of the 4GB HE-AACv2 test suite took 6:49, which is clearly worse than most alternatives on Windows Mobile.

Note that, as with CorePlayer, it supports multiple selections as it uses checkboxes. Note that it allows for switching between different views (Artist / Album, Album / Artist and these prefixed by Genre as in Genre / Artist / Album and Genre / Album / Artist; in addition to this, plain Album title and Artist name catch-ups) using the second icon:

Unfortunately, in addition to the lack of storing the library to avoid having to rebuild it after restarting the player, it doesn't offer too many additional features either. For example, it completely lacks sorting and quick searching capabilities. This was the main reason I haven't included it in the main comparison chart.

2. The just-released Windows Mobile version of Kinoma Play also supports libraries. I'll publish a full review (probably with another update to this bible) later.

3. The recently-released, 3.7 version of Conduits Pocket Player has some enhanced library functionalities. An excerp from the "what's new" list:

"Pocket Player 3.7 enhances the engine that powers its media library and browser in several ways; performance has now been improved through database and file system optimizations, which lead to faster scanning times and fewer track-to-track delays when listening to music.

The Pocket Player 3.7 media browser has also been refined, and is now fully configurable, allowing control over browsing behaviors, such as whether to include local content, network content, or both in the media listings. Users can reorder the browser’s category screen; for example, it can be configured such that the ‘Albums’ option is at the top of the list, and the ‘Songs’ option is on a second page.

Additionally, the media browser now recognizes certain context-sensitive touch gestures, such as swiping left-to-right on an item, or touch-and-holding on an item. These gestures cause actions to be performed, such as adding an item to the current playlist, popping up a menu, or selecting the item for playback. In previous versions of Pocket Player, these actions were not configurable; for version 3.7, these actions can now be remapped based on user preferences."
