Sky's three music channels showed the first signs of life this afternoon by beginning tests on transponder 52.

'The Amp', 'Scuzz' and 'Flaunt' can be found on 10.876V (SR 22.0, FEC 5/6) under the labels '6pt3t', '5pi3oa' and 'rpimby' respectively.

Only EPG 'Now and Next' data is currently viewable, although the first video testing schould begin soon.

A full programme lineup has yet to be released, although the Now and Next data indicates the presence of a jukebox element (similar to 'The Box') on each of the three channels.

Stick with Digital Spy for more on the new channels in the coming weeks.
