(CNN)Music is present in every part of our lives. Our spiritual rituals are framed with songs, children learn the alphabet through song and the malls and cafes we visit during our leisure time are rarely silent.

But just how much can this ever-present thing impact us -- and the way we act and feel? Research suggests music can influence us a lot. It can impact illness, depression, spending, productivity and our perception of the world.
Some research has suggested it can increase aggressive thoughts, or encourage crime.
    Recently, a UK study explored how "drill" music -- a genre of rap characterized by threatening lyrics -- might be linked to attention-seeking crime. That's not new, but the emergence of social media allows more recording and sharing.
      The content of these songs is about gang rivalry, and unlike other genres, the audience might judge the performer based on whether he will follow through with what he claims in his lyrics, writes the study's author, Craig Pinkney, a criminologist and lecturer at the University College Birmingham, in the UK.
