As Gardner pointed out, there are different learning styles. I personally cannot concentrate when there is music on because I get lost in the music. My sister, on the other hand, studies her best with background music- and she is an ace! So music needs to be considered on a personal basis. However, as a language learning tool - it is exceptional when used with popluar, rhythmic and almost hypnotic beats ( think The Weekend, Despacito, etc!)
