To me this song is about how change is necessary in life. They, as musicians, can't stay the same for ever ( We've got to move it / If we want to do our best / We've got to shake it / If we want to keep it fresh). They have to try new things in order to keep creating art and grow as both people and artists. That's why there will never be a second BSSM (like many people would like... not me though... and I love that album).
