Cassette Tapes

My sister bought a boombox from 2008 recently that plays CDs and cassettes and can tune in to the radio and the CD player and radio work just fine so now I guess I'll have to obtain some cassettes to play in it. This definitely isn't an excuse for me to see what's on random tapes, etc. from thrift stores so I can live out my horror/mystery protagonist dreams/potentially discover lost media (which in turn is also definitely not why I bought this DVD last year...)
