If you need to study and concentrate, certain music choices are much better than others.
The best place to start is by searching YouTube. People have put together playlists with hours and hours of back to back music which is great for studying and getting your work done.
You can also visit a website called Coffivity which is great.
And if you sign up for Google Play Music, you will find tons and tons of music resources for studying, motivation, and getting your tasks accomplished.
Classical music is the best place to start, if you haven’t tried anything yet.
