When I get asked to play something, i'll only play it if it will fit in or I have time to change the tempo or style of my set, I've done that quiet a few times if i'm playing stompers and someone asks for a midtempo 70's track i'll change the direction that my set is heading in, so I can play it.
Heres a question for the dj's..
I've been asked in the past for a record that I havn't got, when I've said i havn't got it, I've been told by the person asking that another Dj that has been on has it.. And I should lend it off them, would you ask another DJ to lend a record, I know Andrew said Derek got it from a sales box, but asking another DJ, would you?
I'll be honest here I wouldn't.
