You can't really get the original Hetalia episodes online because they are uploaded in a mobile phone television. The real one is not shown TV since there would be too much debate.
In Hetalia World Series there are 48 total episodes
There are 51 Episodes of the first season in Hetalia Axis Powers.
52 in Hetalia: axis Powers and 48 in Hetalia: World Series including four OVA's.
The new Hetalia episodes is most regularily out on mondays. However, it sometimes take a while for it to be subbed.
Hetalia is a webcomic. The episodes are only 5 minutes long since they animate the comic strips. The is no particular storyline in Hetalia. However there is a movie of Hetalia which should be longer than 5 minutes. But it's not subbed yet
For lyrics go to the hetalia wiki and for actual songs either watch the episodes or you can find most on Youtube.
There are 24 episodes in the first season of World series.
Because most Hetalia fans have short attention spans (including me) XD
