If you don’t have the track they want to hear, don’t start with this phone shit.
What if their battery is down, or they receive a message or phone call while the track is playin?

If it is a private party with just friends, it’s ok. But it’s a no go in a club.

The best way is just parallel buy and download it from iTunes while playing, or have a second laptop, download it and put it on a stick for the CDJ which I prefer

i say no I don't have an aux cord because you will look bad as a dj if something goes wrong

Yeah I would only do this at small party's thanks for the advice.

in saying that I always carry a aux cord incse u have to plug your phone in if your controller craps out

Yeah me too
They can write down the track they like to hear

Usually I have it. But of not, I listen to it online if it fits. If not, I just tell them I don’t have it.
If I like it, i download and play it

On small private party’s make sure the phone is on mute
Just go in the system with chinch to aux and plug your phone in ;)
