Look man, an average song is about 4Megs, right? An average full movie is around 700 Megs, 'k? Well then, if it takes you 4 minutes to download a 4 Megs song, then it should take you around 700 minutes (roughly around 11 hours).
If you don't know what connection you have, then I'm supposing that you are not on a PC that is yours (i.e company or maybe university). That could also mean that you're on a rather fast connection, but I can't really say.
