It depends on the song. The last case in point, I did. But I am reasonably sure she never listened to it. 
We have other issues as well but they are more differences in musical philosophy so I let those be. For example, I believe we should play a song where the vocalist(s) feel comfortable, whereas she wants to play it where she feels comfortable and force the vocalists to move.
dude, its the same thing with my organist. when a song is played in rehearsal to give the choir or praise team a heads up on a new song that we'll be learning, immediately he starts trying to play it (meaning he doesnt listen at all) and i believe whatever get gets from that one sitting thats what he stays with. i dont think he listens to the song at all. ever. and if he finds that the song slightly resembles some other song he "knows" he'll play that instead. Because of that we cant really do remakes like Tye Tribett's "Bless the Lord" or Fred Hammonds "This is the Day" for example, because he wont even listen to the new version and will just play the old standard version instead. highly frustrating.
Its actually so bad, that for the youth praise team, I play keys instead of bass and we just leave him out, because we sing more current songs which would require him to listen and learn the music....and actually show up to rehearsal. And now the regular praise team started requesting I play keys, but because thats not my primary instrument, some songs I just cant play (as well as play in certain keys).
We rehearse on Thursdays, and by Sunday either our director or I have to hum the first few bars of the song so she can know where to go. Not to mention telling her what key we're in. 
I mean, I can understand having a zillion songs in your head, most of which sound alike. But isn't that the purpose of practicing: to separate out the songs so that you know what to play and when?
thats kind of why i hate playing songs that have just that shout run bass line, because everyone then depends on the organist to cue them. But if its a song where the bass can follow the movement of the song, everybody listens to what im playing and take their cues from me and ignore him and let him play catch up.
