For example, the author posted the song "Yamim Al Ye'mei Melech" (which, for the record, I don't know) as follows...
"יָמִים עַל יְמֵי מֶלֶךְ תּוֹסִיף, שְׁנוֹתָיו כְּמוֹ דֺר וָדֺרThe audio clips are turned off right now because of the Sefira period, but they'll be back up soon. I'm looking forward to it.
Yamim al ye'mei melech tosif, sh'nosav kemo dor va'dor
"Days onto the days of the king may You add, may his years be like all generations." (Tehillim 61:7)
The Pashut explanation given by Rashi on this passuk is that Dovid Hamelech is asking Hashem that even if it has been decreed that he die young at the hand of his enemies, Hashem should remove that decree and grant him the full 70 years of every generation...."
