Given the set M={$$- \frac {2}{3}， \frac {5}{4}，1，4$$}, let M<sub>1</sub>, M<sub>2</sub>, …, M<sub>15</sub> represent all the non-empty subsets of set M in order, and let m<sub>1</sub>, m<sub>2</sub>, …, m<sub>15</sub> represent the product of the elements in each subset respectively. If a subset contains only one element, the product is defined as that element itself. Calculate m<sub>1</sub>+m<sub>2</sub>+…+m<sub>15</sub>.
