Basically a standard license gives you the right to synchronize the song with videos on Youtube, internal videos for your business or other corporate videos. However a standard license does not give you the right to synchronize the song with a production that will be aired on TV- or radio channels, for that you'll need a broadcast license.
A personal/non-commercial is the same as a standard license but you can only use the song for your personal/private projects that don't generate any income.
