In real life they reject the idea of writing formulaic pop songs. Instead they work to create music that is interesting, intelligent, energetic, etc. Then they get online and throw all of that away. They post pictures of their lunch, videos that even a used car salesman would be ashamed of, and statements that, if they said them out loud in conversation, would lead to dry heaves. To quote from the movie “Singles”, “Desperation: It's the world's worst cologne.”
If you are going to sell out online, then you might as well sell out all the way. Chase whatever is trendy in music this hour, write boring songs, appear on one of those TV game shows. Although, be aware, there is still a lot of competition down that road. There are already thousands of people desperately trying to sell out in the name of music fame, but they can't find anyone to buy.
Or ... and this might sound crazy … be the same band online that you are offline.
