I mean, tracks that have vocals but not lyrics. It's hard to explain, so I'll just give some examples.

Mavi - Sufi
Head Honcho - Walls of Jericho
Leftfield - Song of Life
Meizon - Aeon
Prodigy - Smack My Bitch Up
Silvio Ecomo - Standing
Cass & Slide - Glad I Ate Her
Paris & Sharp - Aphrodite
Li Kwan - Point Zero
Paul van Dyk - Nothing But You (not too fond of it though)

+ some Shpongle tunes

I have a couple of others, just can't think of 'em right now. I'm looking for prog mostly.
