Mostly i have a little bit of entertainment if i play a tourney. Especially if you play less table you need some more to do as play poker. In the earlier phase of a tourney, it is not so important to check the other tables. So you can here music or look some streams or series. The music can also a little bit more progressiv. If the tournament is half of the itm, you must be more fixed to the game. What decision is the right one, look at your oponnent. What are the players on your table. At this phase you must concentrate. So i hear slow musiv, classic or chill music. It helps to concentrate but did not deflect you from the game. I also think you can control your mood with music. You play more agressiv with metall or hardcore. If you analyze your game and you think you lay down to many cards, that music can help you to get in a more agressiv mood.
