I for one welcome our new Brony overlords. Do us proud, Discord was one of my favourite releases for a while, and though I'm not big on RBN I'll have a keen eye on this thread.
Well honestly we feel that the 2x versions are money grabs as well, but there's a lot of people that ask us to do them (otherwise we wouldn't).
Announcement Post updated to include our first announcements! Go check it out and let us know what we think!
I noticed that some of those songs use voice samples from the actual show. If I remember right, sampling, like covers, isn't allowed in the RBN. You might want to make sure it's okay with Harmonix, and especially Hasbro, to use those songs before going any further.
Edit: Unless you already did both, then I'm just giving unnecessary advice.
Wow, that song with a preview video looks awesome. Really interested in seeing how the rest turn out.
As Megaman768 said, the samples will be removed because of copyright reasons.
Thanks for mentioning it, I added a note about samples in the first post :D
