I'll start with Aqua. I thought Barbie Girl was annoying and just a one-hit wonder. I didn't really like them/their music. I pretty much hated everything and then this song came out and basically ended up being one of my favourite songs of that year. After that I gave them more respect as musicians and went on to love Lene's voice and adored her solo album (which I think I even got on import at the time). Can't say I am a big Aqua fan but this song is still brilliant.
