Crazy i’v been a UK club DJ for 10 years and have had them come in a club i’v been working at once in 2006/7.
They announced they were coming weeks before so I just spun vinyl all night 
Crazy innit? 
What sort of “papers” do you have anyway?
Every mp3 I’ve ever downloaded from Amazon has been 320kpbs…?
seriously, how could they even begin to prove this kind of stuff? do you have to have all your beatport receipts to show them? what about music producers that give away songs for free on their soundcloud, bandcamp, or websites?
Keeping receipts…hahaha. I might be able to find the Amazon confirmation email or the credit card statement, but I’m not going to dig for hours, let alone while working. That’s just crazy.
I agree, it sound a ridiculous, it’s very difficult to prove.
When you look at you beatport purchases in iTunes, in the comments section it says “purchased at beatport.com”, but the the comments are editable anyway! Seems a but daft to me!
What about the issue of downloading an mp3 from beatport, for example, and then burning this to a CD? Surely this is the same but the other way around???
Even DRM’d music can be de-DRM’d…I’m not sure how one could prove that music files were purchased legally or illegally for that matter? With all the different options for buying music, you’d have to know how each tags their tunes and hope the person didn’t overwrite those tags. And then what about all the music that is given away on the net, via blogs or soundcloud, much of which by the artists themselves?
I have been collecting music for nearly 30 years, my itunes has 21k tracks which doesn’t include countless cds and vinyl that haven’t been ripped yet.
How exactly does one look at all of this and determine it was purchased properly 30 minutes before someone’s set?
Yes. What is the word… Some kind of invoices?
Well they may access your traktor list and you have to have with you at all times the “papers”. At least here in Portugal is that way. Of course they won’t see every single music but they may also request you to go to the police station the next day to prove that songs were payed for.
They need to do that in the US. That would eliminate at least 80% of my local competition… Haha.
Xpozur
Yeah but for that club owners should pay more but at least around here a barmaid still gets the double so…
