Default Grinding/whining noise from engine on cold start, alternator/compressor area.

Over the past few weeks, my engine compartment has made all sorts of fun noises.

The power steering pump went out, and was super groany and loud. I had it replaced a week or so ago when it started shuttering at low speed turns. Now i'm hearing this noise on a cold start:

At about 13 seconds is a good one, and again about 23 seconds.

It is a bit louder when first starting the car, and it diminishes to a softer moan, sort of like the pump but not. It isn't coming from the pump area, more the alternator/ac compressor area.

I think it might be tied to the idler pulley or tensioner? I replaced the belts about a year ago at 65k miles, currently sitting around 76k. Any ideas?

edit: It does appear to be linked to engine speed. When I was driving through my parking lot the noise would disappear as I clutched into neutral.

I'm thinking this is normal just because subies tend to be super loud and mechanical as people have said. Though mine makes the same noise and I am kinda interested if this is an actual issue because right now I ignore it haha.

I am going to assume the crank pulleys probably need to get pulled and greased since its an 04 and that is a long time.
