Trying to use a portable CD player - Any Bluetooth transmitter that will pair, or other CD solution?

I've had people laugh at me when I got the thing too: "What, you don't stream?".
I hardly use the thing, mostly listen to just radio, terrestrial and satellite.
I do the thumb drive too, but it is somewhat tedious.
I guess I harken back to the days of going to a concert, buying a CD, and playing it on the drive home. Don't do that much anymore either.
edit: Plus, someone mentioned audiobooks, probably borrowed from the library, which you aren't going to be (legally) ripping.
