Why does some vocal remain?

Modern mixes use stereo vocal reverb, doublers, and parallel effects that are not dead-center. Only the fully centered core cancels.

Does it work on any song?

Best on classic rock, jazz, and old pop with centered vocals and wide instruments. Electronic and heavily processed mixes are harder.

Will the music sound thinner?

Yes — subtraction also removes any bass or kick drum that was summed center. That is an inherent limitation of the L-R technique.
