Mystery box of cassette tapes large

Medium sized tote bin absolutely full of cassette tapes. I truly have no idea what this contains. I pulled a random sample of 5 casettes and found: Rolling Stones, Best of the Bee Gees, kd lang - Drag, one empty case with no cassette, and one in a language I cannot read but that I'm going to tentatively identify as Polish. It could be a fun project for the right person. You can keep the tote bin too! Must pick up!
