Questions about the different distance resolutions between MUSIC and 3D-FFT

Because both MUSIC and 3D-FFT use 2D-FFT to measure distance, then why are the distance resolutions of the two different?

MUSIC is a subspace-based method, it is not using FFT (see here). We use FFT in range estimation while MUSIC is used in angle estimation. I hope this helps.
