....play songs continuously on limewire. My friend says he has tried it before but doesnt remember how to. Anyways if anyone knows how or if there is a feature like that on limewire, please reply. thanks in advance.

It's much easier to just use another Media player. The Limewire one isn't very good.

If you want to use Limewire anyway, then enable the Limewire Player and use the playlist function in your library (Drag and drop I think)
