Please fix this!!!

I love this app but for the past week Ive been having problems with it. If i cut my screen off and back on the song pauses. Some of my songs take forever to load or just dont load at all. Plus the screen response time is late and it only happens with this app. Im not sure if its an apple issue or google. SOMEONE PLEASE FIX THIS!!!
