Was your Hatari album sealed? If not, it was prabably played by somebody. I find that with albums pressed today, in lower volume production, a lot more mold release is applied to insure better quality pressings. HOWEVER, that means it's more important to make sure you remove it before playing the record.
Back in the day, playing the record would eventually get the stuff off (at least where the stylus contacted the groove) because the pressure on the groove with spherical or elliptical styli was much higher than with today's line contact styli.
So if you have a high quality vinyl rig (which you do) and a great (and extraordinarily quiet) cartridge like a Temper W, you're not going to like the sound of today's pressings right out of the box. You have to 'clean' them first.
