My iTunes library is about half purchased via Apple and the other half imported from CDs or vinyl that we purchased.
I almost always verify/correct all the tags when I add a song. I would have said always, but today I discovered an "Unknown Album" containing only one song. The artist tag is Jaci Velásquez, and it does sound like her.
The title tag is "Padre Celestial" but I don't think that phrase is in the lyrics at all. beets can't find a match in MusicBrainz. I looked at Spanish works by her in Discogs, and none of them had that song. iTunes store doesn't have any by her that seem likely, especially not close to the right length, 4:31
As far as I know, we only had one CD and no vinyl from her, and that one is in the library, complete and correctly tagged.
The most surprising part is that I cannot find even the lyrics on line! I tried three different lines, nothing. (That may be because lyrics sites almost always have lots of misspellings.)
It starts out with:
Vengo hoy a tí con corazón dispuesto
Vengo hoy a tí porque lo que más quiero es de estar junto a tí.
I have those two lines in an MP3 but I don't know how to embed it.
Tried Shazam and SoundHound. Both offered me songs by a male, and neither sounded anywhere near this one.
Searched through all her albums in iTunes store and Pandora and don't find it. Yet the file is CD quality, the voice sounds like her, and the accompaniment is a style similar to some of her other stuff. Neither of the first two lines gets any hits in a web search. Mystery.
