sorry, i have never done cassette tape to mp3
i have ripped/copied CD tracks to MP3, and those were perfect
because they went from digital CD to digital mp3
no cables no usb no analog conversion
the wear factor of the tape causing noise in the audio will play havoc with automatic mode, on all but the most expensive conversion gear,
and then maybe on that too
if using that, i would just record the complete side of the tape as one audio file, and label them album name side-1, album name side-2
and not try do to individual song/tracks...tapes arent made that way
not like CDs
