I just LOVE it when my favorite songs play on the radio, especially when it's rare to hear it on there! Like FHF said, the spontaneity is what brings the excitement.
I wish I heard We the Kings on the radio (I've NEVER heard a song from them on radio yet), Tiffany, Yeah Yeah Yeahs, any indie band, and "Borderline" by Madonna (which I haven't heard on the radio since last year! D:)
Lmao, the radio is a big part of my life.

I prefer listening to the radio more than listening to songs by my own choice.
