In Germany there is an infamous organization, the GEMA, who takes money for playing music. This is the reason, why many of the videos you link in here are not playable for me.
If you all could give the interpret and the title, it would be easier to find the music you have given. Thanks.
Because, if our mothers, who have been kind to us
From beginningless time, are suffering,
What can we do with (just) our own happiness?
