wouldn't these be great...you could download a selection of them and listen to them on the way to work.
you get a choice of the best available emotions...chose from one of these great podcasts:
1) Monday blues. The sound of the PMT days; screaming, crying, angry growls and frustrated sighs.
2) Blast from the past. Children laughing, giggles, exclamations of surprise and tears at bedtime.
3)The time of your life. Screams of joy of people on rollercoasters, people booing at a bad band, the babble of confused tourists, the little happy squeak of someone being proposed to, the rant of an ex-employee after being unfairly dismissed.
Take your pick!
