Dar.fm seems to offer exactly the cherry picking you want.

“Many radio stations transmit the names of the songs and bands they’re playing. DAR.fm captures that information and detects song breaks. In other words, if you record a day or so of a music station, you’ve suddenly got a tidy list of songs, identified (and sortable) by title or band. You can listen to individual songs, skip the turkeys and otherwise enjoy your totally free song collection. It’s crazy cool, like a hybrid of iTunes and satellite radio.”
As an alternative, there are many, many inexpensive digital recorders that could record from the XFM radio station of your choice–right out of the headphone jack into the recorder. While the Fuze is a great playback device, it’s cumbersome and low-fi for use as a recorder. But you can get a superb digital recorder for $100-$200, like one of the Tascams on this page:

They have built-in mics because they are for musicians and journalists, but just doublecheck that they also have a line-in jack–connect the XFM headphone out to the line-in and record. There are also little dictation gizmos, like the Sony ICD series, that would probably also do the job.
Just make sure they record mp3, not some weird proprietary compressed format (like the cheapest ones) , and that they have a stereo line-in jack.
The thing is, recorders are larger and not as convenient as playback gadgets like doPi players and the Fuze. You generally have to choose one or the other function to concentrate on–players have better displays and make it easier to find songs or albums or artists, etc.
But really, check out dar.fm. From the description, it seems like that would work for you without going to all the trouble you expect.
