3.0 was obvious from the get go and I was thinking DWD also. But that's probably because I was combing through 3.0 DWDs for clip 1 last week before the "covers" hint came out... Big tip for all you new or inexperienced MJMers. Pay attention to stuff you listen to each week, even if you don't come close to solving. Keep note of how each musician's tone, the sound of the round, how loud the crowd is, jamming themes (funk, space & ambience, etc...). It made sound obvious (thanks mom) but simple things like that and just being observant allowed me to get a lot better at this pretty quickly.

And as a sidenote, happy to see @Bob_Loblaw get his first win. With how many times I've seen you throw out guesses I'm glad you hit one. Cheers!
