It's quite simple.
Every block is related to the music.
You don't collect every block.
That's the end of it. Just because you don't collect them, doesn't make you disconnected, you still get a little star when the block passes the ship, the track itself still follows, all it means is you don't get a sound effect at the same time.
Maybe switching the sound effects off might feel more natural to you?
The only time I feel actively disconnected from the song is when I mess up with puzzle characters and have to miss a load of blocks to fix the grid. But even then you've still got the track itself to go with.
