"A guilty pleasure is an activity or piece of media that someone enjoys but would be embarrassed by if other people found out about it. These might be books, movies, TV shows, foods, etc. Generally, a guilty pleasure is something that might be viewed as shameful by some people, like trashy novels or overdone rom coms."

I love music! Music is one of my favorite time-passers. Although I love songs from different artists, there are some songs of those said artists that I pretend I don't like but in secret, I listen to them.
