If you you are moving your hack over to AddmusicK and do not wish to redownload all your custom music files, then these two programs may help to speed the process up.  You do NOT need to use them otherwise.  In fact, feel free to delete them if you have no use for them.

Do NOT use these on normal AddmusicK songs.  Only for Addmusic 4.05 or AddmusicM songs, and even then, only if you need to add the correct tag to a large number of them at once.

If you drag all your music files over AM4Batch.exe, the #am4 tag will be added to all of them.

If you drag all your music files over AMMBatch.exe, the #amm tag will be added to all of them.

For Addmusic 4.05 songs, you will still need to add the #samples header if the song uses a custom bank; see the main readme for more information.
