Take any decades old underground DJ mixes, from say Dikke Ronny at Antwerp's A.B. (Club), and pass every tracks through Chazzam; the later won't recognize any tracks.
Anyone who thinks that all music ever released on vinyl is available online is either naive or ignorant.

As for music available through the internet, Chazzam couldn't even single out a typical New Beat-style slowed-down remix of "Bostich" by you-know-who. ;)
