首当其冲的就是stereomood，这个一个根据你的心情来播放音乐的免费网络电台。

First up is stereomood. It's a free Internet radio site that plays music according to your mood.

现年34岁的网络电台创始人艾德里安·马丁内兹说这个电台要在宠物“家长”外出工作时跟宠物作伴。

Founder Adrian Martinez, 34, says the station aims to keep pets company while their "parents" head out to work.

如果你听的是网络电台，看看网络是否提供有博客节目(数字广播技术，网络广播或类似的网络声讯节目)，博客可以让听众实现倒退和多次反复听同一个片段的功能。

If you're listening to Internet radio, see if the website has any shows as podcasts so that you can back up and listen to a segment several times.
