I got the question from someone today if I had any advice for him as an aspiring producer who wants to be signed on Macarize. I thought about it and one thing came to mind. No matter what label you want to release your music on, you should make sure that the music you plan on submitting is equal to the stuff on the label or preferably even better. Try to be as honest as possible to yourself and don't rush things. If you on the other hand don't feel that your music is as good as the stuff already released on your favourite label, maybe you should go back to the drawing table and make the necessary adjustments in order to give your track that extra edge.
To achieve this you need to be very self-critical, patient and have honest and skilled people around you who constantly help you with feedback. If you time after time send material that aren't on par with the rest of the stuff, you will slowly become less interesting for the A&R's and if you're really unlucky, they won't even listen to your next submission. I know this may sound harsh, but it's the truth.
So, to sum up, be prepared and give it all you got and a little bit more before you approach ANY label.
