This quote is saying that when it comes to art, like music, it may take a while to really understand and appreciate it. When you first hear a song, you may not automatically like it or understand the message that the artist is trying to convey. However, if you keep listening to it and really pay attention, the song might start to appeal to you and you might start to understand its deeper meaning. This is the beauty of art: it takes a while to really understand and appreciate it and can mean something different to each person who listens to it.
