Now I tried the plugin but it didn't play all my music automatically I still had to press play.
With the default settings, Windows Media Player Plus! in fact only starts playing music at WMP startup if music was also playing at the time you closed WMP. Perhaps this wasn't the case when you tested it?
Can I create a smart playlist as in everytime one folder (i.e. my music folder gains an additional song) - WMP would automatically update the playlist I have already created.
Do you know if this is possible and if so, how do you make a playlist like this?
In WMP's library, click the arrow next to
Create playlist, select
Create auto playlist and enter a playlist name. The default auto playlist will contain all of your songs but you have to add at least one criterium (right under
Music in my library) for the
OK button to become available.
A good candidate for such a criterium is
Sort by Contributing Artist Ascending order. After adding that, you can press
OK and you will have an auto playlist that contains all of your songs and that will be updated automatically.
