One possible connection is that both can be a form of escapism. A paperback novel takes you into different worlds and stories, and Nickelback's music can also transport you to different emotional states or memories. Their music, like a good paperback, can be a way to get away from the daily grind for a while.
Nickelback and a paperback novel can both be forms of escapism. When you listen to Nickelback, you can get lost in their music, just as when you read a paperback novel, you can get lost in the fictional world it creates. Their music has the ability to take you on an emotional journey, similar to how a novel can make you feel different emotions as you progress through the story.
It's possible that some fanfiction writers have combined these two universes in creative ways, but they may not have gained widespread popularity. It could be because the combination is a bit unusual. However, on platforms like FanFiction.net or Archive of Our Own, you might be able to find some stories that blend Naruto and Nickelback in interesting ways.
Often, they are portrayed as charismatic and sexy. For example, in many novels, the rockstar is shown as having a magnetic stage presence that attracts the female lead.
One idea could be Naruto characters performing a Nickelback song at a shinobi concert. Imagine Naruto on stage singing with his raspy voice trying to match the tone of a Nickelback song.
It could mean that Nickelback's music or their story is like a paperback novel. Maybe it implies that their music has a narrative quality similar to the stories told in paperback novels, with different 'chapters' or phases in their musical journey.
