Well I like iTunes. I come from 99% mac use, but use it on my PC as well. I like that it organizes my music collection, I hate having folders all over the place and iTunes does a great job at keeping it organized and in one place. No accidentally moving a folder and it can no longer find it. Easy to go through your entire collection of music, or make playlists, smart playlists for when you want specific things. It stores your movies as well, same was as it does your music, though the formats will be limiting compared to apps like VLC. I convert everything to mp4 anyways to work with my Apple eco system (iPhone, iPad, Apple TV, multiple macs) and it works great. Good quality and the file sizes are not outrageous for a 1080p video. It runs fast on my PC, though people do complain about it being sluggish in windows, just not my experience. Could be because I am running an SSD.
