How do you discover new music?

Usually, while watching YouTube, I see songs that I haven't heard yet. Chances are, I will like the song. I also often listen to songs that are/were used to make memes, such as, for example, in the past there were memes with ascending SpongeBob, in which the song was Wolves by Kanye West. After the meme "died", I still kept listening to Wolves because I really liked it.
