When we launched our new Song & Arrangement pages, we changed the primary action for clicking on audio & video files. Instead of downloading them when you click, now it plays the file in the media player, and downloading is in a secondary button.
Today we've expanded this to PDFs and image files. When you are in one of our new updated pages (Profile, Song, Media) and you click directly on a PDF or image file, it will open up a preview of the file right in your browser, giving you a way to view it before downloading.
You can download from the preview using the Download icon at the top right. However, if you don't need to preview a file, you can still download it quickly by clicking the download button that appears when you hover your mouse over a file, or simply type 'D' on your keyboard while mousing over the file.
