Historically, PG Music never predicts the future or tells their marketing plans. Having said that, in the past PG Music has used song contests as a method to increase use of new or interesting features.
In this instance, Xtra Styles differ enough from traditional Realstyles that PG Music sponsored a contest. Contest songs provided audio content for users to hear Xtra styles in use beyond the demo songs.
Did I hear you ask how do Xtra styles differ from Realstyles? In one way they don't; Xtra styles are Realstyles because they use RealTracks. However some Xtra styles also use loops. Each Xtra style uses a non traditional group of instrument RealTracks and have a more modern approach to the mix.
