This applies only to Classic View mode:
Right-click column-headings in Library to get Column options. Different options for each Audio & Video, etc. sections of the Library window. Click or double-click the column heading to arrange the Library files in that order. When arrow points down (after double-clicking), it will show maximum at the top. In sample image below I've shown arranging the Library via most Hits (my files found in other people's searches), & most Uploads.
