Listening to music while working isn’t for everyone, but if done right, it is promised to help you work better. Or at least that is what the startup focus@will is promising. The music site wants to help you get into the “zone” and keep you working with music that isn’t going to distract you. There are more details on their site if you want to read more about the science behind it.
There are no ads on the site. What you get a three-week free trial period and after you can only listen for 100 minutes at a time or pay the monthly subscription fee of $3.99 for unlimited access.
