*tries Bored.com's song tapper* Actually, that's pretty good, provided the song's been entered in the database and you can tap on each lyric syllable (you might accidentally tap the melody).
*tries melody you put up* No help. I wish there was a database of songs with nonsensical lyrics, one that would include that "I'm a Scatman" song and the blue da ba bee song (I was so embarrassed when my parents were trying to write down the lyrics to it).
Drives me crazy when I remember the melody of a song but can't make out the lyrics (or they're foreign or the lyrics are just aah aah). On top of that, Google doesn't have links for lyrics to some songs. I'd like to know each song that's used in Louie Devito's "Dance Factory Super Megamix", but I can't identify some of them because typing their lyrics into Google doesn't help.
But I was able to discover that a song I was looking for since childhood was Michael Jackson's "Earth Song". I knew it was that one because it was right around the year I deduced it occurred, I thought Jackson was female because of the high voice (explaining why I remember the song being sung by a woman when it wasn't), and it had the same sort of melody.
There was some other song I heard in a store sometime, and I tried to keep the lyrics and melody in mind all the way home, but couldn't. Another potential song lost. And I couldn't ask anyone what it was because the song ended almost immediately after I noticed it. Stores need to start having electronic things saying what music they're playing, because there's usually a wide variety of music and some of it's good. One time at the grocery store I heard Phil Collin's "Something Happened on the Way to Heaven". I still find the idea of music in a grocery store strange, but whatever.
EDIT: I didn't find it, but "Kiss From a Rose" by Seal sounds to me a lot like what you're saying. Doesn't sound like dance-techno though and it's from 1994 (won a Grammy in 1996). Some nonsensical lyrics, "a light hits the gloom on the grave aah-ee-aah".
YouTube video here (ignore that it's a Final Fantasy X AMV).
The part that reminds me of your melody is 1:16 - 1:21. I like the song.
EDIT 2: There's also " Stealin' " by Uriah Heep, that's got the church sounds in it and "oo-oo oo-oo ah ah ah oo-oo oo-oo ah ah ah" and a lyric near the end has the only instance of the word "grave". It's a lot closer to what you're looking for, but it's from 1973, it doesn't quite sound like techno, and it doesn't seem fast-paced.
There's also Dj Cammy's "Ah Ahh Ahhh" (it goes under a billion different "Dj" names and other artist names, it's the same song but remixed I guess) which is indeed techno, but you mentioned oo oo so I don't think that's it either.
