The Windows Phone app typically runs $1.99 in the Store but for the next twenty-four hours, you can pick Core Music Player free through the myAppFree partnership. In just tinkering with the app briefly this morning, it does take a short bit to get used to Core Music Players' navigation. Otherwise, the app comes across as a solid music player option.

The number of quality Windows Phone music players in the Windows Phone Store has grown significantly over the past few months and Core Music Player hopes to turn a few heads with its file-based player.

Unlike other music players that automatically scan for music files, Core Music Player relies on you to sort out what files you want to access. Support is present for mp3, mp4, aac, flac, wav, wma, 3gp, 3g2, amr, m4a and mpr formats.

Key features of the music player include:

File Management: Open, delete, rename, copy and move any type of file

Folder Management: Create, delete, rename, copy and move any non-system folders

Music Library that can be sorted by artists, albums, songs, genres, years and support for background sync

Files can be searched by keyword or reviewed by your playback history

Sleep Timer

Folders are pinnable to your Windows Phone Start Screen

Playlist creation with support for shuffle playback, sort by name, manual re-order and duplication

Playback controls tiles and album artwork (if available) add to a simple, clean playback screen. Playback can be single or multiple files, playlists or your music history.

Core Music Player comes across as a Windows Phone app with potential but takes a short time to become accustomed to. Core Music Player normally sells for $1.99 in the Windows Phone Store (there is a trial) but through the partnership with myAppFree, for the next 24 hours you can pick the music player up free.

If you try Core Music Player, let us know what you think of the Windows Phone app in the comments below. Also, remember to rate the app in the Windows Phone Store to give the developer feedback on their works.

Please note it may take some time for this deal to show up in the Store due to the various time zones involved.

Update: We just heard from the folks at myAppFree and apparently there were technical problems in launching the deal today. Look for free deal to kick in sometime tomorrow. We'll keep an eye on things and update the post when we see the deal go live.

Update 2: Just checked and the deal is live in the Windows Phone Store for the U.S. Market and should be live elsewhere as well.
