Music format: light rock / soul / jazz / inspirational / gospel music.

Source: the offiical IOMIB website, July 2006:

"The Station will not focus on one type of music to the exclusion of all others, i.e. there will be a broad selection of music types and an extensive music play list. It is likely that the mainstay of music heard will be light rock and soul, with significant jazz and blues plus some inspirational and gospel music,"

So, that's light rock / soul / jazz / inspirational / gospel music.

The SPECULATION is that "inspirational and gospel music" points to the Christian (religious) bias of the output of the station.

Indeed, the FAQs from the now removed longwaveradio.com included:

"For the record, we are a group of private investors in the Isle of Man, the UK and the USA, who are in this as a purely commercial profit making exercise. While many of our shareholders are religious, none practice with any more fervour than regular worship and none are involved in cults, as far as we are aware. One doesn't need to be very religious at all to enjoy gospel music – just look at the success of 'the Blues Brothers' film, and they were on a Mission from God!"
 
On the 'inspirational and gospel music' planned as part of the main output, the FAQs said: "It's fine uplifting stuff (well most of it) and sadly lacking from today's radio."

On the official IOMIB website in June 2004 there was no mention of 'inspirational and gospel music'.
