Don't know if there is much interest in this now as someone posted this in 2016 and only got 7 TU.
Works for current subscribers, you just have to validate your edu email and select student as the option. This comes out to $60 a year for up to 4 years.
The link I'm posting has all the info but here is some copy/paste:
If you're a student at a degree-granting university or college, you can join Apple Music for a discounted membership price for up to 48 months (4 years). The time does not need to be continuous.
The Apple Music Student subscription is only available in certain countries and regions. Learn more about Apple Music availability.
When you join Apple Music as a student, UNiDAYS, a student validation service, confirms that you're enrolled in a degree-granting university or college.
Periodically, UNiDAYS re-validates your student status. If UNiDAYS finds that you're no longer a student or if you have a Student subscription for a full 48 months, your subscription automatically becomes an Apple Music Individual subscription.
*To note, I have my edu emails forwarded to my primary email address. However, the emails from UniDays did not forward for some reason and I had to validate from my actual college mail inbox so you may want to check every now and again if you do the same.
