From 
http://www.popullar.eu:
PopuLLar is a European Union, <EU Projects  
 > funded, innovative, education project designed to harness music, 
the primary social interest of secondary school students, in to their 
language learning. 
There is a huge need to motivate secondary school
 students, in particular, to learn languages, focus digital competencies
 and be creative; and music is the key.
The project will ask students
 to write their own lyrics to songs of their choice. They will then 
translate their songs in to the target language they are learning, The 
students will then record their song (audio or video) and share it with 
students all  over Europe. 
Students will be able to combine their 
love of music, with creativity, literacy, digital competencies, group 
collaboration and, most importantly, use LWULT languages. 
PopuLLar 
is a project that is 'Owned' by the students, they work autonomously and
 collaboratively, teachers are guides to the project process.

NB The PopuLLar project does not so far mention captioning/subtitling. However, subtitling tools might be extremely handy towards its goals.
