I bought after testing the Standard version. With the Premium upgrade it is possible to get & save favoured artits and titles. That is great. Also it is possible to work with favourite stations besides the genre stations. It is important that you choose with options your favourites AND limit the bandwith. F. e. 4 favourite stations with 128 kBit/s = bandwith 512 kBit/s. If you limit the bandwith this way you will get only your 4 favourite stations. In general I am a fan of radiotracker, because the handling is mostly very easy and the features are special. Other streaming software that I have tested often have two problems: 1) not enough or bad radio stations for streaming 2) handling is bad. Radiotracker uses 8.000 shoutcast radiostations AND is easy to use.
