Not when season seven has about six "Everybody is obsessed with a 1960s crooner holodeck recreation" episodes and ...
I read of a general dislike of the Vic Fontaine holo-character, and Vic's lounge, with more than a few fans on this board. While admittedly not my kind of music, I found the whole Vic Fontaine experience to be nice. For the DS9 crew to spend time in Vic's lounge (or play a single baseball game) during a war, is no different than the Enterprise's crew going to ten forward during a war when they'd be off shift.
That said, I personally didn't care for Badda-Bing, Badda-Bang, but not because of Vic Fontaine.
