Why aren't the archived mixes available? Is it because of licensing? Why doesn't RA post them on MixCloud or another service that pays out the appropriate royalties to the license holders?

Does RA prevent users from uploading the mixes to MixCloud themselves?

I just wish there was a legitimate place to listen to all of the old mixes.

Some of archived mixes are available at MixCloud : http://www.mixcloud.com/tag/resident-advisor/
