Hey Jessica, as far as I know, Music4 dont make the sweepers I am after. Music 4 just make the DJ talk beds, feature Jingles such as One Big Weekend, Sport Relief etc, Newsbeat, Moyles, 1tros ... everything that carries the radio 1 logo 'do dee do do'. What I'm after is made by the inhouse station sound department, using the custom sound design elements [the whooshes/crashes/bangs] from a jingle company thats name has escaped me. Radio 1 add in the voiceovers and mix these down to create the audio you hear over the 1tros/in and out of links/over beds etc. These mix downs with the DJ or show name checks is what I'm after, I know its a long shot, but worth a try. PM me if you have what I'm after, as I said I have quite a large collection if you'd like to trade. All the best.
