yeah mobjle djs play a massive part. for every wedding or xmas party i have ever really enjoyed, the dj has killed it. and i dont mean beatmatching or mixing in key, in fact the best ones you forget theyre there. but by controllong the vibe of all the night they can make a formal boring event to an awesome event!!! where everyone is just going wild and having a good time. and ive been tk some crackers. and even more so im sure more than once when a xmas party has been shit the biggest comment is damn the music sucked tonight. so sol definitely dont sell mobile djs short. they play an important part, which is somewhat harder given the range of ages, personal tastes, length and formal interuptions.
