Here's the tip on how to record songs from disk to tape out jack on ][e:

Ingredients:
A two way earphone jack (male)
Copy ][+
Some Assembly language experince
The disk with you favorite song on it
-------------------------------------
1. Boot up Copy][+ and load the sector editor
2. put the disk in drive two (Or whatever drive you have slected)
3. Hit "R" for read, and type: 0001 [RETURN].
--The disk should spin a little and some text and hex will come up on the
screen.
4. Hit "S" for search, and hit "H" for Hex. Then type: 30 C0.
[RETURN]
--The disk should spin a lot or a litte depending where the sound routine is.
* hex $30 C0 is the address to click the speaker, thus making sound if
repeated fast enough (At machine level speed.).
5. Once the drive has stopped then hit "J" a few times to move the cursor back
a bit. then type "L" for list and see if you can find: $C030 anywhere in the
listing, if you couldn't then goto 4 again.
6. If you did find it then hit "B" for beginning then Search again for it,
this time (Now that you verified that it wasn't stray data.) hit "J" ONCE.
Then press "H" for hex entry. Then type 20 [RETURN] [ESC]. Then hit "W" for
write to disk (Remember this should be ONLY DONE ON A BACKUP!!!) and hit
[RETURN] twice. After the disk stops spinning skip back to 4.

                USE THIS METHOD ONLY ON A BACKUP COPY!

Now for the Button addresses
$C061 (-16287) -- Peek this address to see if the value is larger than $80 or
127 in dec. If the value is larger than 127 then the button (Key) is being
pushed.
 
$C062 (-16286) -- Same as above but applies to PDL(1) intstead of PDL(0)
