Hmmm, usually when you search for a song, first comes the result for ‘Artist - Song’, which is the individual video. Then a couple items down comes ‘Mix - Artist - Song’, which is the mix, also identified by an icon.

As for Gruuthaagy, I asked because it's a pretty obscure Croatian noise artist, whom I first discovered via torrents. For a long time, he was nowhere else to be found except in pirate uploads on YouTube — now he's also on Bandcamp. Similarly, YouTube is the sole service where some other records are present, especially for free.

If I recall correctly, you mostly have records locally. But, as a victim of multiple failures of physical media, I would recommend keeping a list of all those records — and then you can conveniently link them to online services so as not to fiddle with the local records each time. For this purpose, I link my notes to Bandcamp and YouTube in that order of preference.
