Cassette tapes only get eaten if the tape path in the deck is not kept clean.
Same thing with Reel to Reel. This is what almost all music recorded before the year 2000 was recorded on.
I will take analog tape for longevity over any digital format.
Anyway, on topic; I had a 40MHz 030 in my A1200 and the best I could do using mpega from the command line was 11.025KHz (Quartered) Mono without the audio stuttering. So instead I used mpega to decode the files to AIFF files and then played them using play16.
