Many times I have downloaded a music file and later struggled to find the performers and dates. Now after I make a download and while I am still viewing the post, I press "Print Screen" in the upper right hand corner of the keyboard. Then go to Microsoft Word and right click anywhere on the blank page and click on "paste". Save the page as a Word Document in the same file as the music download and you will have the information when you need it.
Yeah, same process can be done in MS-paint while you want to upload album-art in form of .bmp file...
