Our sharing of music came by sheer accident.
When we have the studio pretty much to ourselves, we also have free rein of the stereo system. We bring our own CDs, and CDs that I have burned through various yo-ho-ho-and-a-bottle-of-rum methods of procurement. This includes several "non-traditional" cha-chas (Love Shack- B52s, Yeah- Usher/Lil' John, etc.), and so forth. Well, one night I left my CDs there- forgot them. The next week, we arrived early at the studio so we could stretch and stuff before our private lesson, and what do I hear but "YAYAH!"... "OOO-KAAAY"... "HEEY"... There are two of the instructors having the time of their lives, grinning like idjits, dancing a cha-cha routine they just slapped together for the Usher song. That Friday, at the party, a too-familiar song started playing... "If you thee a faded thighn at the thide of the road, that thayth fifteen mileth to the.... LOOOOOOOOOOVE SHAAAAAAAAACK!"
... we looked at each other, and then, naturally, the other couple who sometimes sneaks into the studio with us to practice (with teacher consent) looked accusingly at us- we shrugged, and then went and did cha-cha, while everyone else was sitting there with this ... "Wha??" expression. It was hilarious.
The key to getting "your music" played at the studio is have it actually match what's done there. Songs that are too fast, too slow, "undanceable" to your typical studio dances, etc... they won't be played. Check and make sure the music you use is of a close enough tempo and style (I Wanna Sex You Up by Color Me Badd was a good Rumba, but the connotation might be questionable to the senior population of our studio, for example), and if it has appeal. A friend of ours loves a particular artist of standards. The problem is that the artist doesn't keep tempo- he's one of those like Bing Crosby- he might sing a song, but it's "all over the place" with no measured, strict meter/tempo/etc. and he doesn't understand why this doesn't work. So, of you don't have an "ear" for it, be careful- like the one guy at our studio who thinks that EVERY dance is a samba. I'm sorry- I've never once heard Dinah Washington sing a samba....
