Both SAM Broadcaster and SAM DJ have a set of default categories under "Content" and "Special" in the "Playlist" window. We call them "Smart Categories" because they group tracks based on a common feature.
When you right-click on a track, select "Song Info." In this window, under the "Info" tab and near the bottom, you'll notice that the file has a "Type." Here are the different types SAM Broadcaster can attribute to media files (you can also change the file type manually in this window):
S: Normal song
I: Station ID
N: Syndicated news
X: Sound FX
C: Unknown content
So, for example, under Content > Music > Music (All), all the tracks found in this smart category should be marked as Type "S" to indicate that they're all "Normal songs."
You'll find other smart categories under "Special," also in "Playlist." These include "Weighted Rotation," "Overlay," "Song Rights," and "Play Limit."
The categories under "Groups" in "Playlist" are read-only files. You also can't drag new items into these categories. However, they're ideal for locating tracks from a specific artist, title, year, genre, or album.
What makes the smart categories so clever is their ability to edit data to match a category. For example, if you drag and drop a normal music file into the "Sound FX" category, it will automatically change that song's setting to Type "X." In other words, you won't have to change the song's type in the "Song Info" window manually. You can even drag and drop multiple files into a smart category and change their settings in one quick motion. This applies to all smart categories except "Groups."
After you edit media files in "Song Info," hit F5 to refresh your smart categories.
