Deane, keep in mind that I'm at the lower end of age category for those NH residents. And, there are some a fair number of years younger than me. Consequently, the stuff I liked when I was 15 to 30 years of age is the same things they like as well. Also, I agree wholeheartedly with Don - you have to please the staff as well as the residents. Granted, I will play some 40s stuff, Glenn Miller, Nat King Cole, etc..., and that all goes into the mix.
I'll try to convert my MFD (music finder directory) to a PC readable format and post it. They are my go-to songs for most events, but like you, I have about 3000 or more songs programmed so I can instantly access them at the touch of a button, most of which rarely get played at all.
Cheers,
Gary
