You got a few replies. What you were asking for had an extremely limited scope bearing in mind there aren't that many active members on here. Solo work has a narrower appeal, and the Swedish stuff especially isn't that well known to most fans.
You then said that people could just rate what they knew, but that made little sense as, if you really were wanting to compile a list of most popular songs, the English ones would have an unfair advantage. Plus, as was said in that topic, most people were giving 6, 7, 8 or 9 to most tracks so you'd have ended up with some dull totals.
Don't be too disheartened, but also don't expect the active members on here to have the same level of interest that you do in certain subjects. It doesn't work like that. Orf made some comments in another topic that I didn't necessarily agree with but he did have a point. There's a lot more to life than rating ABBA members' solo work!
Pop Justice (a forum) has a thread about ABBA (and it's English), but that plays a small part on their website since Pop Justice focuses on more modern artists like Lady Gaga, Björk, The Weeknd, Florence Welch, Taylor Swift, Pharrell Williams, and such. You might get drowned in that thread (metaphor) as it changes from "Will ABBA ever come back" to "Hey guys, I'm gonna spend a vinyl record", and to "The ABBATRONIC!" quite fast, from what I've observed. The site doesn't seem to acknowledge Anni-Frid Lyngstad or Agnetha Fältskog as a honing solo artist, so I'm not too engaged in the Pop Justice thing.
Therefore, maybe I thought ABBAChat was made specifically for the big limelight of ABBA and its related links.
In spite of my statement, I love the "Fridatronic 2000/3000" idea that some people did, it's fun that they acknowledge Frida as much as Agnetha. There's nothing like adding humour to a thread
