Like Kaloyan said, more info may be needed. Preferably the city it broadcasted from (not just where you were picking it up) if you know it. Then again, if you know that info, you'd be able to look that info up online better than us. After all, if we find a possible station, you'd still have to check it out for yourself to see if that's the one. And if it had a name like "Energy", then it's likely one of those chain stations that have similar ones all over the U.S. KISS FM comes to mind. If you're just looking for techno/electronic/dance music to stream online, check out
http://www.di.fm/ It's got nearly every electronica genre you can think of for free streaming (or paid for higher quality sound, but the free stuff always sounded great to me) and you get a choice of streaming protocals like straight MP3 or WMA.
