A genre is a loose set of criteria for a category of composition. In Lips, the game recognizes a set of genres when a song is pulled from an external media player in the Get Music menu. Among the recognized genres are:
The Holiday songs require the player to download a special preset set of custom videos available only on the Xbox Live Marketplace in order to have a custom video shown at the background. It is worth nothing that these songs are only available during holiday season (november-february usually). However, in Lips: Number One Hits, the Holiday custom videos are included by default, which means players do not need to download the custom videos that were available during winter 2008/2009.
If Lips fails to recognize the genre, it will play a preset video featuring abstract shapes.
