I still have tapes, the only ones I miss playing are ones given to me that I don't even know who the artist is to look it up on Youtube.
The other Obscure music I have on Tape is also on Youtube, with many live versions and much higher quality recordings than my old worn out tapes.
google youtube to mp3 converter. Identify the banner ads which will proclaim DOWNLOAD in larger letters than the actual clicky for the actual mp3 dowlond clicky, and do not click on those.
I have an old cassette player not much larger than the cassette itself. it runs on 4.5 volts DC. I have not tried it for years but I suspect the rubber bands driving the gears inside would not live very long were I to reemploy it.
