The Voice is a decent song, but clearly not my cup of tea. To me it's somewhat overrated. It doesn't really deserve to be on top. As you say, Rock 'n' Roll Kids are so much better. But then again, we can't like them all.
I loved most Irish entries from the 90's, but my favourite is undoubtely:
1.THE VOICE
also good songs:
2.Mysterious Woman
3.Somewhere in Europe
3.Rock'n Roll Kids
4.Is Always Over Now?
5.In Your Eyes
6.Could it be that I'm in Love
7.When you need me
