i reckon you should still post all artist links. if a topic only has a few posts and gets buried without being archived here, we run the risk of someone else starting a thread on that same artist/band. a quick merge for the mods, sure... but might as well keep it as thorough as possible.
speaking of, since you said you don't have much time, i'll start/maintain a genre/catch-all thread so you can remove the ones here when it's up and running. i can maintain it as i'm generally on here all day while at work.
