Have you ever listened to a radio station - on YouTube? I just found these video streams that go 24 hours a day and play nothing but chill study music. It's been a blessing at work when I need to just to zero in on a project and the absence of lyrics helps keep me focused (otherwise I start singing along and get distracted). I am currently loving this chill hip hop beats channel (if doesn't hurt that I love the film Wolf Children where this anime clip is from too!):
There are tons of different types of music available, so if classic or electric are more your concentration vibe, there is a stream for you!
What helps you focus when you have a ton of work to do? Please share your secrets!!!
