1080 kHz unid 1980s rock music

[Zoidberg]

Almost a year after a previous unid on 1080 kHz I'm still trying to sort out a couple of unidentified stations heard under my local KRLD between 11 pm and midnight.  Before midnight I can null out KRLD just enough to copy what seems to be two very different stations, but can't pinpoint them via the online reference sites for MW stations.  After midnight apparently these stations power down because only KRLD is heard clearly.
9/22/09
1080 AM (w/ local KRLD nulled out)
Since 11 pm, heard Prince "Little Red Corvette" and "Raspberry Beret", Peter Gabriel "Red Rain", Cyndi Lauper "She Bop"
11:42 pm: Possible ID, Spanish language, not sure if same station playing rock music.
11:56 pm: Spanish language and Tears For Fears "Shout" heard overlapping, so 11:42 pm ID might not have been same station playing '80s rock music.  Apparently these two are swapping skywave fades under KRLD.
12:03 am: Orchestral music with choir, sounds like some sort of anthem in Spanish.

Doesn't seem to fit KYMN (Minn), WUTT (Tampa, FL).

You can search fcc.gov for AM stations in Mexico:

I get Mexican AM stations here in San Francisco, although I don't pay much attention to them. I'd be surprised if one plays 80s music with English lyrics.
