This is great news. I have signed up!
I must say, despite of how awesome Sync for Reddit was, I think we should all try not to go overboard with our expectations of what the first version of Sync for Lemmy will be. This is testing ground for all developers and expecting the same level of polishment that an app had on its 22nd version might be detrimental to the actual experience.
We know what ljdawson is capable of, so let's support him, let's enjoy his work (I am sure Sync for Lemmy v1.0 will still be awesome), but let's also give him time to refine his product on a new platform. I don't know what is involved in the development of this new app, but I do see some points where all other Lemmy apps are struggling, so I can only assume this enterprise presents some new challenges. It is only fair to give him some room for growth and not expect absolute greatness from scratch.
Sometimes yes, but it depends a lot on the book. Also, each book might call for a different type of music. Best fit I can think of, was listening to Beethoven while reading The unbearable lightness of being.
Either way, always no lyrics, and often try to avoid songs I know so I can't hum or sing along.
