Madonna ruled the summer of 1985 when "Into The Groove" was released in late July. The song featured in the actually quite funny film Desperately Seeking Susan, and became a massive hit. After the success of songs such as "Like A Virgin" and "Material Girl" Madonna seemingly could do nothing wrong, music-wise that is. "Into The Groove" is actually one of her very best songs, I think. A true classic!
