This lyric appears in the song "Don't be trendy, don't spend money", excerpt of the lyrics: Sometimes a flash of inspiration occurs, Newton also eats apples, my thoughts are not too long-winded, I have a limited time to be seated, please, Don't buckle everywhere, the trend needs to be dignified, and if you are not careful, you will not dig it wooh. "Not Trendy, Don't Spend Money" is a swing dance-style song with a brisk melody, retro style and personalized lyrics. It not only expresses JJ Lin's understanding of trends, but also makes the song more nostalgic. In the music arrangement part , JJ Lin uses house elements appropriately, which is refreshing. At the same time, it breaks the audience's previous listening inertia. I didn't expect that JJ Lin can also make swing music so trendy.
