Good afternoon.  Unfortunately, I badly know English, therefore I have translated this message by means of the computer translator. Therefore I apologize for possible logic mistakes in the text.

Here there is an interesting offer which I yet did not meet in other players.

Each of us would not listen to what music - any person will have compositions which like him more than others. And compositions such as a rule not one and not two and at all ten.
Also happens, that you wish to include a player and easier to listen to the favourite music, having cast away on a back of a chair or having collapsed on a sofa. As a result this invention as a rule is reduced to search of folders and separate compositions, their addition in playlist, and, at last, to the listening during which constantly you understand, that one to add has forgotten, and the third has got in playlist casually.

Meanwhile that capacity which computers possess is not used. And it was as though good, if in a player there was only one button which starts constantly updated list of favourite melodies.

And in fact to realize it not so it is difficult. We shall allow a player will trace all compositions listened by the user. If any of them has completely lost in a player of 5-7 times, it is automatically marked as a favourite composition

And by pressing the magic button the program makes and starts playlist consisting of the favourite songs generated by a player

First, it is very user-friendly! Only one button and from columns flows favourite music.
Secondly, the library of compositions will always replenish itself with new songs.
Thirdly, I think it it will be not so difficult to programming

Thanks for attention =)

I think there are a couple of ways to get what you want, right now. First, dynamic playlists are a part of Amarok, in the Playlist tab. Secondly, if you use last.fm for awhile, you can stream their "recommended radio". Have you played with these?
