Lyric discussion by ZinbobDan 

not sure who said it earlier, doesn't look like anyone is talking about the meaning now anyhow...i think this song is clearly about a boy who has it really bad for a girl and he's willing to do anything for her but he keeps getting rejected...so he finally invites her into his "room of musical tunes" where they hav sex? he kills her? that's where his insanity kicks in...but, let's remember that it seems most of syd's songs are about being wronged by a girl, so i sometimes think the chaotic ending expresses his desire to kill her (tho i don't think he ever did)
