I just wanted to give a positive comment, specifically about the things that people are giving negative comments about. The website design isn't boring, and emphasizes that the app differentiator is that it's looking to be a better design and have things like "album art first".
Electron does have a small resource problem, but that doesn't stop plenty of people from downloading the desktop version of Slack, or other popular electron wrappers. There's a reason a lot of people put up with Electron, it fills a gap.
Whether you did this to try Electron or design, comments on HN can be very subjective and not representative of actual reception. I personally never thought album art was super important cause I grew up with Napster, but like "cover flow" was REALLY well received. Artistic design is especially highly opinionated.
