Rant about brother in law

So my brother in law lives with me and my husband and lately he has been driving me nuts and today just totally put me over the edge. He is obsessed with music and buys any instrument me wants whenever he wants and play them til two in the morning some days and we live in a freaking apartment. Here I'm 39.1 week pregnant and me and my husband has turned and have went I wonder what he is going to do when he finds out he can't play all of his instruments when our son is born whenever he wants. He is probably going to get pissy like usual if things don't go his way. Right now he is trying to get out of paying May rent by saying he payed it when he payed Aprils but he didn't. Then to top off everything that has totally pissed me off is last night he had his friend over (which is a friend of my husband so that's okay) and they made a thing about going to Taco Bell this morning for breakfast and was like let's go as early as we can maybe 6 or 7 in the morning. So my husband asks if I wanted to go and I said yeah I'll go and it hit like 11pm and I was like I'm going to bed so I can hopefully wake up a little easier. Well last night my husband fell asleep out in the living room with his brother and friend when he told them if he did wake him up so he could come to bed with me because he has a hard time going to sleep in the bed. So they didn't and I guess the friend woke him up sometime around 6ish and my husband walks into the room and lays down and falls back to sleep with me. About 7am comes about and I just wake up to my brother in law basically screaming at my husband for falling back to sleep and everything just cursing him out and so he gets up and asks me if I still wanted to go and I said yes basically to spend time with him but his brother was just being a complete asshole and was like your taking 20 years to get ready to my husband and I told him never mind just go without me because I didn't want his brother to throw a fit waiting for me to get ready. And so my husband gets ready and he is still just cursing him out calling him names and everything and it was just pissing me off. My husband comes to kiss me goodbye and say he loves me and his brother starts complaining about how long he was taking and they weren't going to have much time to eat breakfast now. At this time it was 7:10. Like seriously can't you wait 5 freaking seconds and act like an actual human being and not be an asshole. I'm to the point I want him to move out but we need him for the case of rent until I can go back to work. I keep feeling like I am going to blow up on him and am just waiting for the day that my son is born and he learns my husband can't just drop everything and take him places or go anywhere with him just like that or even the whole instruments playing them. I'm sorry I just needed to rant.
