Delete files from source and not just playlist

i, yes, good idea, and I would add that it would be great to have the option of either deleting from the current playlist or deleting from the source (i.e. permanently deleting from the source drive, whether local or cloud). I find this feature really useful because sometimes I hear a song in my collection that I know I want to get rid of permanently, and it's waaaay easier to do it straight from the music player rather than having to track it down in your source drive. Thanks
