Although generally I'm not very interested in gadgets, the radio bookmark got my attention. When you're listening to a public radio station and a story or song comes on that you'd like to hear again later, you press a button on the radio bookmark and it remembers for you.
Fritz Kreisler's Liebesleid (Love's Sorrow) is a song that I bookmarked.
The version that I heard on the radio was on this album. (I didn't see a video for this particular one.)
