Good post Near North. When i was there recently there was a mix of music played at Mambo Jambo. The dj will play whatever you request...
Mambo Jambo has had to adapt a bit, as their bread and butter were the cruise ships across the street that were in until midnight or 1 AM. There are precious few of these currently. So, the all-Latin programming probably had to give way to keep whomever they get in happy.
The remixes that the DJ does at Jimmy's on Thursday (really fresh new mixing of 80's and 90's songs) is a lot of fun.
I've never been much for the Senor Frog's YMCA/Celebration tourist mix.
I also suggest catching Marisela's band at Bugaloo on Sunday nights, no cover.
