I am looking for some components:
1) A component that desplays lyrics in a panel in foobar
2) A component that helps me rate my mp3s and keep statistics how many times a song was played and when, when it was added etc.
I tried some but didn't find what I want. Which are the best ones?
Thank you!

If you want to use default UI, the lyrics is not supported yet. You can use columns ui for ui instead, and use lyrics then.

Install foo_playcount.dll for question 2. Available on foob's optional componentpage.

Thank you!
I installed foo_playcount.dll, but the only place where I can see statistics is mp3s tag. Can't I see statistics in foobars UI? In colomns near the tracks title, duration etc. I use the default UI.

You need to add columns to the default UI with the code you want to see. (preferences > playlist view > custom columns

example columnpatterns:
$date(%added%)

$pad($repeat(★,%rating%), 5,✩) (use this if you have arial unicode as font, replace the stars with another symbol if you dont use arial unicode)

%play_count%

%first_played% or %last_played%

%played_per_day%

Thanks!

Everything works great and it was very easy.
Is there a way to add rating by left clicking on the stars?
And I wish I wouldn't have to change fonts.

Font changing is neceserry for those stars. I use hearts with normal arial font.

You can't implement that leftclicking rating in playlist view. the best options available when using default ui for rating are:
1. define keyboard shortcuts for rating 1, 2, 3, 4, 5 in preferences > general > keyboard shortcuts

2. rightclick buttons in menubar, choose customize buttons, and add buttons for rating 1 to 5. (use pictures of stars for example)

Mar2zz, thank you! Your advices are allways very helpful!

Is there a way to see the most played mp3s or the top rated ones?

No answer for the question above?
I guess it is not possible..

Do a query on:
%rating% PRESENT SORT DESCENDING BY %rating%

or these:
%rating% GREATER X (X represents a number of rating)
%rating% IS X
%rating% LESS X

In all cases you can change %rating% for %play_count% to get times played results.

Thank you again!
