Whether something counts as fact spamming in my book is largely dependent whether or not anyone would find it interesting. Since there are a wide variety of E2 members, just about everything will be interesting to somebody. Hence the name Everything2. The other dependence is by whether the author has stretched one node into many, or decided not to compact a large number of tiny tiny nodes into a few, more organized nodes.
I do think that a comprehensive listing of all magic cards is fact spamming. First, it is formulaic and available from better sources that are easy to find on the web. Second, it grants each card one node - doing a single expansion set will provide the author with around 300 nodes, enough for level 5 on its own, provided that the author can come up with the XP. Of course, the administration does not take levels very seriously, but it provides a sense of scale.
However, even simple lyrics listings aren't fact spamming. Some people want to know that stuff, and might not know where else to look. It also serves as a starting point for any further writing on the subject of the song. But also, it's a matter of scale. Noding up the lyrics from an album would yield twenty nodes at most, as opposed to the 300, above. This does not diminish my opinion that they are cheapass writeups. That is to say, they do not bespeak much of the author: anyone can do it, but also anyone can find a reason to do it - so no information about the author has been gained. Therefore, they won't get much in the way of up or downvoting from me.
In the end, it is best to Earn Your Bullshit by writing good nodes, whether they are factual or not. If some of your factual nodes are a little out there, consider them part of your bullshit quota.
