I am not able to delete individual songs in my collection, I've tried adding them, again, deleting, adding the whole album, then deleting. They still appear but only on the web access (I use MacOS (Safari)), on my iPhone app they do not show up? I've also tried using google chrome to see if this makes a difference but it does not.  I've tried deleting history, cookies, cache, etc. It will still not delete these tracks out of my collection.  Thank you  ...
