I have found 4 examples of music with a connection to chocolate among previous participants.
Among the chocolate songs this time there is music from Southpark, latin, rock and rap. Among the artist you can find 4 Non Blondes, Lil Jon, Hayes Isaac, Shanice, Alex e Alex and more.
Here are even more chocolate songs. This time there will be both carneval and hard rock, with artists like Emilia, Danko Jones, Snow Patrol, One EskimO etc.
This time I will give you chocolate music in german, spanish and english. Mostly slow music with a few exeptions. Kylie Minouge, Russel Crowe, Trude Herr, Rufus Wainwright, Wood Brothers among others. Some songs are actually really good.
