Owl, you're assuming too much as to what I have for tunes......or more correctly, what I don't have.
I'm not an over the top song fanatic with multiple CDs, tapes, etc. I enjoy country/jazz/blues, etc. and have no use for rap and that kinda sh**.
So even though I have a few CDs and quite a few cassette tapes of "oldies", I have absolutely no (folder) as you put it of songs, etc.
Since the new bike has no CD drive, I was looking to take advantage of the power cord deal and the little compartment to store some device that could play whatever I wanted to play.............Of course, I would have to understand how to load (whatever) device this might be.........with whatever tunes I decided upon.
I'm an old retired guy that worked for the Itty Bitty Machine Co. but given that, had no real software expertise to help me with this problem.
