help for a research

[maoxiang]

Hello friends:

I am postgraduate and doing a research about special music training course market, such as DJ training and recording artist training course.

I wonder where I can find the relevant articles that introduce the insight of this market in Nethlelands, or Germany, or Portugal.

Alos, could you tell me in Netherlands, or Germany, or Portugal what's the most popular magazine that people who are interested in DJ and recording art would like to read.

Thank you!
