Best tracks for studying
There are lots of different methods of studying, but the most common theme I hear people say is they need music or some type of noise to help them focus. When most people say that they have music playing I typically think of classical music. However people will usually listen to music that they like from an individual basis. However if you are the type that likes to to listen to repetitive and instrumental songs then you need to check out "Lofi hip hop mixes"
There are a tone of these live broadcast that are titled as "Lofi hip hop....." and they are all wonderfully relaxing beats. Each live stream has a different theme. Some have a study theme feel and others have just general hip hop feels. I would highly recommend them if you're just trying to relax or have some type of background noise.
If you are looking for more cool and relaxing hip hop music for studying I would recommend soundcloud and other live stream searching for "Melodic Trance streams". Those are also great options to help you relax, study, or just general music enjoyment.
