Genie, I apologise if you have a serious use for a karaoke machine, but I base my observations on the many ghastly uses they are usually put to.
And yes I do have an aversion to watching somebody sing accompanied by a tape soundtrack.
But if an artist is useing a keyboard and has some pre-recorded material that is used as part of the synth or whatever(I don't realy understand how these things work)I don't mind. In fact just listen to Chris Harvey in Strawhead to see how good it is.
But someone singing along to a tape? no not for me.
Cheers
Les
