Seems that I remember many people having on and off problems with Stream On. However to be totally fair, I've never used it. I like StarPlayr because of the cool interface and the ability to show the nice channels icons for the presets. I also appreciate the developers as they are staying on top of making any changes and fixes almost immediately when needed.
StarPlayr will be adding the artist/song alert feature eventually, after all this is still in an alpha version, but thus far has been very stable.
But it is good that we have a choice that meets our particular needs. I look foward to your comparison with the Stream On software since I've never personally used it. Honestly most of my streaming is done via my Stiletto SL2.
