The problem with Google Play Music, Spotify and similar services is that you must select the music, which can be incredibly distracting in itself. I like music radio stations better in that regard.
Digitally Imported (https://di.fm) is a fantastic voice-free radio network with over 300 channels/genres [1] for every kind of music (electronic, rock, pop, jazz etc). I use it every day, it's hard to not be productive while listening to their Goa-Psy channel [2].
I originally found this link on the HN front page years ago and have kept it bookmarked. It's got lots of good suggestions like this. The comments on the post have great suggestions too.
Thanks for that link. I already listen to half the artists mentioned in the article, so I’m interested in checking out the others. I only recently discovered Tycho (who sound very similar to Ulrich Schnauss) while God is an Astronaut (along with Mogwai) have been on my play-list for the past decade or so. I’d also recommend minimal techno and the second wave of Detroit (Carl Craig, Kenny Larkin, etc.). I spend a lot of time listening to Warp records from the 90s. When I really need to get stuff done, I reach for Fuck Buttons (best listened to with a player capable of gap-less playback).
i decided to pay for google play music, it's probably my favorite paid service since i got it almost a year ago.
cmd.fm and jamendo are also pretty fantastic
