I've only seen one song so far, but it's a tiny shift.
They've seemed to have added to regular rotation Mary J. Blige- "Family Affair" which was released in 2001. (I believe B101 has it in their library as well.)
WOGL has tossed some 90s tunes in recently as well, including Green Day- "When I Come Around" (1994), Natalie Imbruglia- "Torn" (1998) and REM- "Losing My Religion" (1991)
