When do you get the new songs they promise – Piano - Play Keyboards & Music Review

I read that you get “Thousands “ of songs , I purchased this product back in February . And I thought the new songs would come every Month. but I have not received any new songs as of April 20;2019. Has anyone received new songs since you purchased this product ? If so ,do they appear in my list of songs or do I need to down load them some how.? PS. I do love this App! But I would love it more if I got the songs that was promised .
