That’s almost the exact opposite experience for me. Maybe there’s been a more recent update, but I remember searching for specific phrases in decade old messages and the gmail (web site) search would just flat out refuse to show things but I could find them from my phone. I’ll try again, but to be honest, I’ve somewhat given up on google search in general for results that aren’t recent.
The Dash Berlin ASOT 600 set (specifically Sofia) got me through my dissertation writing. Even now, if I sit down with a coffee and turn on the set, within the couple minutes I am completely in the zone for working. It’s like a brain hack for me.
I also like the Music for programming site (specifically RITES) which is also good for some focus music.
I’ve tried to get some folks to post their dissertation writing music and form a massive playlist, as it seems really common to have some certain song or album. I’m sure it’s similar for other intense work flows too.
