Write a playlist, containing uptempo punk music, some songs with metal and rock/rockabilly influences, also containing some ska songs. The songs could be popular in germany, some songs may be in german. The energy of the songs should be fine for both playing the playlist at a party, or having it play in the background when visiting friends. The bands and songs should not be too mainstream, aiming for more of an underground sound. Let's also include some Volbeat, NOFX and similar styles. They playlist should have 40 songs.
