It is amazing how much music can unite people. Traveling around the world only proves that. Even though you and your new friends may not speak the same language, a round of beers and Wonderwall can bring everyone together. So traveling with solid number of covers in your brain can go to a long way.
The more the better when it comes to the amount of songs to know, but I’ve noticed that the more bizarre the cover the better. Pick up a huge 90s one hit wonder and watch people lose it. Fun times indeed.
