So at work, I listen to various different online radio stations depending on the mood that I am in. Radio 1, Digitally Imported, Slam FM, hot mix radio, Fresh FM, m1 live and XM radio. My current fav is XFM. They play the current best hits of trance, electro, and everything in between. They have a good mix also of classic songs by the well known Dutch and Belgian producers. Clearly this is a great place to listen to great songs before they get played.
Another great feature that they have is that they post their playlist for the entire hour on their website. Its easy to navigate and gives u a chance to find the cool song u just heard.
The only down side is that they don’t have alot of DJ shows. they do have Armin’s ASOT and De Jong’s Intuition, but that’s all i’ve heard. My #1 radio site.
