Daytime vs Nighttime use of Lyra and Demus

I had almost quit using Lyra since I couldn’t get but 1 or 2 songs played before Lyra just wouldn’t play anymore. Today I’m playing before noon and every song in the playlist is playing without any problems. I’m beginning to think YouTube is causing all the problems at night as their servers get overloaded by normal YouTube users plus Lyra and Demus users. I don’t use a login so could that be a problem at night?
