Don't waste your time writing a lengthy cover letter to this company. I applied a couple of months ago, and they didn't even bother sending me a standard rejection email. Very unprofessional.
From my experience and for the music I listen to, Discogs has much more detail compared to Musicbrainz.
I think a good 50% of my local music is missing from Musicbrainz.
When the release is present, almost always it's missing different issues for the same release (e.g. the white label test pressing release, the final release, the restamp from 20 years later). Discogs almost always has all of them.
Discogs includes lot of useful information: is that specific release single sided? Was it pressed on acetate rather than normal vinyl? What had it etched on the runout?
I can't spend enough good words on Poweramp. Expecially if you use an external DAC, it's the software you're looking for.
It's been thr first app I bought on my first Android phone running 2.1.
The developer behind it kept delivering updates, improving compatibility with the quirky audio stack of some smartphones and introducing actually useful features.
The interface doesn't follow the latest user-hostile trends, having instead its own consistent style. Nonetheless over the years it's been constantly polished. The huge number of features and settings are not limited by the interface which actually provides discoverability for them.
For the audiophiles, the audio pipeline is extremely customizable. For the tinkers the interface is very customizable and APIs for writing plugins with are provided.
When I look at a language I could not care less about the selection of keywords, the syntax used for a loop or the naming conventions. What I look for are the means of abstraction that the language provides, and Go gives nothing more than C.
I don't use Spotify just because whole genres are not there. And I'm not talking about some obscure music from 150 years ago. Even Jungle Tekno from the early to mid 90s can't be found. The only sources are some 50 years old random guy fondly remembering their MDMA-fueled glory days and uploading their records on YouTube, vinyl from Discogs, or private trackers.
