Add WCSM 1350 in Celina. They're a Music of Your Life affiliate, or were last time I checked.
Also, WRBP-LP 101.9 FM in Delaware (north of Columbus) is a hybrid of soft AC, standards, and instrumental easy listening.
WLEC, WBCO, and WILE-FM are all Dial Global affiliates, WIOI is a Music of Your Life affiliate, WERT is a locally programmed standards/oldies hybrid, WHTX is locally programmed standards/soft AC (I wasn't aware they'd switched back - good to know), and WMKV and WKHR are more nostalgia/big-band oriented non-comms. Not sure what WJEH does though I've been trying to find out.
In eastern Ohio, depending on where you are you should be able to pick up CFZM 740 out of Toronto and/or WJAS 1320 out of Pittsburgh.
