With Youtube track manager : "Search for similar artist / Open artist and similar artists" search results are quite good. Best than with "same artist station" of Youtube Radio.
My idiot question of the day: why do you call it "Youtube RADIO"?
For me radio is ...a radio station. I'm confused in my playlists of web/stream radios and youtube radios.

@Mire777, I made search tests with the same artist, with different results. Your script is on my installed foobar and WilB's script is on a portable version.

Anyway, there are not many people posting here.

About radio...my confusion could be because I don't use last.fm. Its'not a problem

I could rename, but I'll have to remember to rename again everytime you update

Deezer, Echonest, Jango, last.fm and Rhapsody all seem to use radio
Pandora, Rdio and Slacker seem to call them stations
Spotify seems to use artist radio

So I don't currently have anything better to suggest since use of the terms radio or station are pretty standard ways used to describe artist and similar artist and genre type music playback by a number of well-known sources. Even though it is a little confusing compared with traditional radio. So I guess "radio" now has a new meaning...

For me, simple lady not very intelligent, radio means web radio /streaming radio. I choose radios for classical music, jazz, pop or news.
About Youtube Radio, for me it would be easier to call it Youtube music.
Today, I'm trying to have a new skin and make test on a foobar portable version where I have only the foo_Youtube component. It is more easy, no need for panels, buttons and scripts to find artists songs, concerts... 
Surely I miss important things.

You can download all tracks by clicking ''convert''. You can also download ''lame''(for converter) - and save all tracks as mp3. If this is what you need...
You can also automate this proces if you want to download all songs you listen in one folder, but i think that this is not good idea..
There might be songs you love and other you do not love.. So better is that you do: ''right click>convert'' only for songs you love.

How to automate??

function on_playback_new_track() {
p.item_focus_change();
LOAD_ART();
}

function on_playback_new_track() {
if (fb.ActivePlaylist==(GetPlaylistID(pls + " ["+ STATION +"]"))) {fb.RunContextCommand("Convert/Record");}
p.item_focus_change();
LOAD_ART();
}

function on_playback_new_track() {
//if (fb.ActivePlaylist==(GetPlaylistID(pls + " ["+ STATION +"]"))) {fb.RunContextCommand("Convert/Record");}
p.item_focus_change();
LOAD_ART();
}

First go to playlist, right click on track>convert>...
Make new preset with name ''Record'' enter 'path' where you want to save tracks..

Then:
Hold Shift>left click on YT button>configure
On line 45 you have this:

Code: [Select]

function on_playback_new_track() {
p.item_focus_change();
LOAD_ART();
}

Replace this line with this:

Code: [Select]

function on_playback_new_track() {
if (fb.ActivePlaylist==(GetPlaylistID(pls + " ["+ STATION +"]"))) {fb.RunContextCommand("Convert/Record");}
p.item_focus_change();
LOAD_ART();
}

Now when you play YT Radio, foobar will save all tracks in user defined folder.
To turn this off, comment out this line with ''//'':

Code: [Select]

function on_playback_new_track() {
//if (fb.ActivePlaylist==(GetPlaylistID(pls + " ["+ STATION +"]"))) {fb.RunContextCommand("Convert/Record");}
p.item_focus_change();
LOAD_ART();
}
