I'm convinced some quiet background music can increase productivity or at least I'm willing to try :) I'd rather listen to music on head phone than street noise.
I believe that music should be definitely non-vocal, it should not have any recognisable melody that is "singable" and it shouldn't be too rythmic.
Now I'm not an expert on music genres. Do you have experience or can you name a genre I should look for, when searching for "unsingable", non-rythmic music?
