We had a thread exactly like this a year or so ago. It ended up being dozens and dozens of pages of names of bands and songs or albums. In other words, incredibly boring and nothing that anyone in their right mind would want to read! The question with threads like this is: what is the ratio of people who are genuinely interested in knowing what other people are listening to, to people who just want to show everyone how great their taste in music is? I'd wager that there are going to be a lot more of the latter than of the former.
Basically what I'm saying is that threads like this are kind of like an internet version of farting: loud, obvious, maybe mildly amusing on a really slow day, but ultimately nothing you'd want to be in the vicinity of in the long term.
I'm listening to Pneumonia, by Whiskeytown.
