Sorry it took so long, but I wanted to come up with another one of my patented 4-parters! Here's the deal, there are 4 songs, all of which are related in some way, like the same word in each title for example. At least a couple of them should be easy, which can give you clues to the last one or two. You have to get all four to move on. Give it a shot!

Hint: #4 isn't a rock/pop song - no artist needed, I even gave you the translation.

1. I never thought it would happen
I feel quite the same
I don't want to hurt you anymore
I never knew it would work out
No one to blame

2. Ah! bwakawa pouss, pouss
Ah! bwakawa pouss, pouss
Ah! bwakawa pouss, pouss

3. Hielten zich fur Captain Kirk
Das gab ein grosses Feuerwerk

4. Seit umschlungen, millionen
Diesen kuss der ganzen welt!

(trans. - Be embraced, you millions,
This kiss for the entire world!)
Run, run like a fire
