unlimited oldies, depends what it is.... price is $9.99, but don't expect to get all your favorites..... There is allot, but its defiantly not complete... No streaming service has every piece of music ever. Just not gonna happen
Apple music offers free trial for 3 months to try it and see.
Just a slight correction: It will work on an iPod touch. Of course besides being an iPod it is also an iDevice and won't help the OP's iPod shuffle situation.
