This little Stupid Project of the Day (SPOD) converts exported MACAST (MacAMP) playlists to GrayAMP playlists. It will not convert normal MACAST playlists, they must be exported via the 'Export Playlist' menu option.
Instructions
1. Open MACAST, and the playlist you wish to convert.
2. Goto File:Export Playlist, and then 'Export to Text File...', save.
3. Open GrayAMP Playlist Converter
4. Select 'Convert Exported Playlist' from the File Menu
-Select the exported file from above
-Save new playlist
Know Issues
MACAST's exported playlist format is not the best. It contains the full pathnames of the songs (ex. Macintosh HD:MP3s:Song.mp3) followed by a Return. So if in the path of your MP3, there is a Return in a folder name, this will confuse GrayAMP Playlist Converter. This is rare, but still possible.
