Linda, I have had that happen too with some muffins sticking to the paper liners, but not others. This is the way I remember which ones to use paper liners and which ones to use foil liners. I have noticed that the muffins made with butter do well with paper liners, but the ones made with oil stick, so I use foil for those. The way I remember is "oil use foil". That has been my experience anyway. I use paper liners for cupcakes. I've never greased or spayed any liners and never heard of it.
