When you hear a song you like — even if it's halfway over — one press of a button records it from the beginning.
Once you record a song to the Helix's memory, that's where it stays. You can't burn it to a CD or transfer it to a computer; you can't move, copy or distribute it in any way.
When you hear a good song, you bookmark it on the player.
The player also offers a TiVo-like "wish list" feature: you plug in the name of a band or a song, and if that band or song ever comes on while you're listening to a different channel, the radio alerts you so you can tune in.
