It's important to keep innovating, move forward and improve existing idea's. The same goes for pop-music. If you look at the history of music you can see that every great artist imputted something new into their genre. Take Nicolo Paganini for an example. His violin works are fenominal and innovating because he created new and different sounds and at the same time managed to keep the genre exactly where it should be.
Thomas is not as good as the greatest minds from the past but he is working really hard to create beautiful and meaningful popmusic, so that other people can enjoy a famous genre with a new touch. !
