I don't know about all that. There's plenty of software out there that is much more complex and isn't as bloated. Granted multimedia software can get pretty 'heavy' but still. I feel like iTunes for Windows is very low priority and fewer resources are allocated towards it which I find a bit sad, I used to use iTunes for years and now I rather just listen to music off my phone or from a browser from Google All Music Access.
Although even my Google Play Music app seems to have some annoying bugs lately that are starting to irritate me, like if I download songs for offline listening and I'm connected to the internet it still redownloads the song. Or how it always winds up failing to download albums for offline listening despite it streaming just fine at the same time.
I mean I thought we solved playing audio files ages ago, most people listen to pretty standard audio files so I'm surprised we dont have snappier apps to listen to music with. I can totally see an Electron app emerging that gives a better experience than iTunes, which is embarrassing given how many resources have been allocated to iTunes as a whole.
