Therapy (formerly Trance Around the World), Aly & Fila's Future Sound of Egypt, and Markus Schulz's Global DJ Broadcast. Special episodes and celebrating events Although the program usually takes the format of a mixture of two hours in which the latest musical developments are presented, special episodes are also made: broadcasts of recorded sessions, the programs in which the Tune of the Year is chosen, the Year Mix, the anniversary editions, as well as various specials. The 100th episode was a 5-hour special show, with guest mixes and the best tunes of the 100 episodes. The 200th episode was a 4-hour special show, with the most requested songs by listeners, a Gabriel & Dresden guest mix, and one hour of a live show from Amsterdam. Since the 250th episode, and every subsequent 50th episode of the show, there are some celebrations that include guest trance DJs that play live. Since the 400th episode, these celebrations have often taken place in different countries. In March 2011, during the Ultra Music Festival, A State of Trance was given its own stage as part of its A State of Trance 500 Tour. Since Ultra 2011, A State of Trance has had its own arena at Ultra and the Electric Daisy Carnival in Las Vegas. Since the 500th episode, A State of Trance's annual episodic celebrations have effectively replaced Trance Energy (later simply called Energy, focusing on electro house instead of trance) as the main trance event in the Netherlands, where every year the biggest of these celebrations takes place. Regular features Each regular broadcast features five songs selected as Tune of the Week, Future Favourite, Service for Dreamers, Trending Track and Progressive Pick. The Tune of the Week is selected by Armin van Buuren as his personal choice of best new tune in the show. The Future Favorite is voted for by listeners from a list of new tunes from the previous week's show. This section began in episode 090. The poll takes place at Future Favorite. For Service for Dreamers, Armin asks the listeners of A State of Trance to submit original suggestions for a trance track that has had a meaningful impact in their lives. During episodes 248–769, when it was known as ASOT Radio Classic (and between episode 770 and 799 as Armin's Oldskool Classic), Armin would select a track from past years and briefly describe what made the track
