I have just imported my last FM scrobbles yesterday (but music I listen to is mostly not scrobbled at all, because not played on PC) with the web importer.
There would be no proper/easy/straightforward way for me yet to submit my listens (foobar2000 in Windows XP and 7) because I don’t feel like building a complex setup just for that and because it apparently won’t be compatible with XP anyway.
I don’t have any MBID in my rips, usually…
The few tracks that are clickable lead to recordings different from what I have played (like for instance they link to studio version instead of live, etc.).
I don’t know why some tracks are clickable.
The most surprising thing is that in this case, artists would have been more easy to make clickable but they are not.
