I felt like Dirty Computer was a big letdown on my initial couple listens. But I put it aside for a couple weeks and came back to it and ended up quite liking it. The album drops off after Make Me Feel, but up to that point it's quite consistent. Electric Lady had a lot of great stuff but I really felt the length (unlike Archandroid which feels about 10 minutes long to me), and that's less of a problem with DC. "Screwed" and "Take A Byte" stand out to me the most.
The Brian Wilson feature was kind of a non-entity since he was just going "ooooh" in the background.
I find it interesting that everyone seems to have vastly different preferences when it comes to St Vincent. I suppose that's the mark of a great artist.
