I love the Beatles, I love music from the 20th century, I take inspiration from it as well as so many other people do. However, believing the best music comes from the 20th century while not being completely wrong, also is far from completely right. There are SO many good artists and bands, other than (but not forgetting, because there are good songs on the radio) the ones you hear on the radio. Don't group all modern music into one genre, there are hundreds of different genres. Stay away from the "all modern music sucks" phase, cause it just makes you turn sour. Keep an open mind, don't be a brat.
