Seconding this recommendation. The more electronic- or instrumental-oriented songwriters on the show tend to get more into the nitty-gritty details of production, layering sounds, etc. (the first two episodes with The Postal Service and The Album Leaf, for instance) while rock and singer-songwriter types tend more towards the songwriting aspect (the Long Winters is a personal favorite).

I sort of wish there were more technical details as a rule, but it's understandable given the relatively short format that they can only cover so much ground. I'd prefer longer episodes personally, but I suppose not everyone might, and there's tradeoffs in producing more content. I guess I'm just glad that the show caught on and is still going strong.
