Yes, that's right. Okay, its not strictly liturgical necessarily, but here are two places you can go to get traditional liturgical chant, polyphony, etc.
From the East:
Ancient Faith Radio
Description: Ancient Faith Radio provides high quality 24 hour internet based Orthodox radio. Here you will find music, teaching, interviews, features, convert testimonies, conference recordings, and much more.
Good online streaming chant from the Christian East.
From the West:
I don't have a link, but AOL's online radio stations includes a "Renaissance" category, the vast majority of which is renaissance sacred polyphony. I found this through "Winamp" which includes these radio stations -- and will incidentally also work with the station above as well.
