sentences:  Pinkberry officially received the Live and Active Cultures Seal from the National Yogurt Association on April 17, 2008, almost 3 years after the initial "real yogurt" lawsuit was filed.The Pinkberry jingle heard on its Web site is sung by the 1980s musician Tigra, from L'Trimm.Apparently in response to the recent lawsuit against Pinkberry claiming that its product is not "real yogurt", for a while Pinkberry had removed all lyrics to this jingle on its Web site except for the word "Pinkberry", which repeats over and over again at the chorus (prior to this change, the jingle had lyrics that characterized Pinkberry's product as "yogurt", and compared its product as better than ice cream).
