@Riot Musical Copyright question

I'm the editor on an amateur student short film project (one of several our class is doing right now). It's a 3-4 minute comedy piece in a dojo/zen type environment, and I'm trying to find some Asian-themed music to go along with it (I'm specifically thinking about this year's Lunar Revel login music). Would I need to go through certain channels to legally use the music for a project like this? or is it fine as long as Riot and/or the appropriate composer (most likely Christian "Praeco" Linke?) is credited? If it helps, this short film is low-to-no-budget, and is not being distributed for profit in any way.

If the boards aren't the appropriate place to ask this, we can pm in the client or something. I'd like to hear back in the next week or so if possible.

Thanks in advance for your help. :)
