I searched through this forum and I don't believe this site has been mentioned before.
Unfortunately these times seem to be very busy for me. I seldom have enough time to try and learn the lyrics to a new song. So what I often do is if I don't already have the lyrics to a song I like in a document file, I'll search for it and play the song while reading the lyrics. Well today that search brought me to Lyricstraining.com. Now it's a site where you can pick different languages to practice a language which I believe takes you to Babbel, or you can scroll down to pick from songs in the language you chose. Now I went down to the bottom row and started clicking on the right arrow to see all the videos they had and they had a great selection of songs and singers such as Libere Delivree (Disney) by Anais Delva, Derniere Danse by Indila, Le Sens de la vie by Tal, Elle ma dit, C'est bien tot la fin. Other songs by Zaz, Amel Bent. M. Pokora, Shy'm and not to mention the song ACC by a beautiful young singer named Alizée!
Once you select a song, you can choose different levels and what it will do is on the easy level, play the song and show the lyrics except for a word here or there that you have to fill in. On the harder level (there are 4), you have to fill in every word. They have a red progress bar at the top. If you take too much time, you are done. Now I didn't register. To continue, I think you have to register which will allow you to continue, or you can just refresh the page and start again.
They say they use their own cookies and third party cookies, but I don't think that's much of an issue at this point.
Once I selected ACC, I saw if I scrolled down, there were several other Alizée songs listed.
It would be nice if they had the English lyrics too, but still, I think it's a good learning tool.
Edit:
I tried registering and it didn't seem to make a difference. Once that red progress bar ran out, you were done and had to refresh. But if you chose the practice mode, you could take all day and I found it was kind of fun. Now normally it stops every couple of lines, but if you know the song fairly well and can type in the lyrics quick, it keeps playing.
