Pops and clicks are not typically broadband, very little noise of this type is and I would not take a broadband approach to this material. Did you listen to it?

Pops and clicks have a fast rise-time which allows one to separate them from the music, with a more-or-less surgical approach. In the time domain.
Broad-band noise reduction is much harder, and is usually approached as a "frequency domain" FFT/IFT type problem. Picture a 1024 band graphic equalizer, with a threshold set by the noise "estimate," and if a band is below the limit, it gets attenuated, etc.
Taking LP clicks out is relatively easy.
I picture, somewhere, CMH, and JAM laughing the laugh of the truly carefree...
At me.
