Madhurashtakam is composed by Shri Vallabhacharya. He was influenced by Madhwa philosophy. He started a Bhakti movement and evolved "Pushti Marga" where you constantly worship Lord Krishna. Madhuraashtaka also is a stotra on Krishna, here he describes everything associated with the lord as Madhura or Sweet. Ashta means 8, this stotra has 8 verses in it.
