The first trick is finding them, and the next is playing them. Fortunately, with a little information, both tasks are rather easy.TUNE IN To find an Internet station of a particular genre, start with the basics: a Web search. Type in “60s,” “NPR” or “Catholic” and the words “Internet radio” and you'll come up with a list and links to those channels.Another useful source is streamingradioguide.com. The Web site lists more than 14,000 stations that can be searched by genre. While extensive, the list is not complete.Internet radio hardware and smartphone apps that offer radio transmissions don't typically accumulate station offerings themselves; rather, they use aggregators, companies that create a selection of channels. On the Web, you can access radio channels directly from those aggregators as well; they include Reciva.com, Radiotime.com, Vtuner.com, 1.fm and Freeradio.tv.via Internet Radio Stations Are the New Wave – NYTimes.com.
