I heard the track that plays during the loading screens for SAB levels (https://www.twitch.tv/videos/330675684?t=18h31m49s) being played a lot during ANet's 24h Extra Life stream.
This is the only SAB track which hasn't been uploaded to the soundcloud, and the stream is where I heard the full-length version of this tune for the first time (the SAB level loading screen never takes that long, so we never get to hear the full tune ingame).
Will more music be made for SAB?
The SAB race could use a catchy tune instead of the peaceful music that plays by default in the hub world.
Also, please upload the Guild Anthems (https://wiki.guildwars2.com/wiki/Natasha_Foxsong) to the soundcloud too.
