Already have previously bought a lot of noise records and CD's and wanted to see how the times now with downloading this same direction is the case and how since the quality of the goods is just so. Now first times made me naturally already the length of the tracks pleasantly surprised. Otherwise, those tracks always yes only maximum 30 sec - 60 sec. Here, however, do not. Next the sound throughout is really Polyphonic and really absolutely realistic, probably because included in nature. So this is good track just so not only for dubbing video or audio plays, but also to relax. But when I see another application will also give me the opportunity so while reading in children with this very To let sound accompany, he is long enough so that. It is so with me for a top and successful product.
