But even so.it's still a hard sell to a youngster if the majority of styles in an arranger are tailored to the 50 and over crowd.

I've long said that arrangers shouldn't try to do everything. A lot of them (most, nowadays) can radically update their ROM styles, even sounds. Why not allow the store to install the ROM pack they think would best suit their customers? No reason why they can't sell an additional style pack to cover missing genres, but if at least 3/4 of the ROM styles in an arranger were tailored to a 20-year age demographic (16-36, 37-57, etc.) I think a lot more kids would buy into them...

And there's nothing to stop a store updating the ROM if Mom & Pop walk in and might like an arranger with the older stuff in it. Keep all the Ibiza and Deep House stuff off of their arranger, keep the Elvis or bigband stuff off the kid's arranger, much easier sell...
