downloading music worth listening to on a computer


It seems to me that every recording I've heard downloaded to a flashdrive or DVD on a computer sounds fairly hideous. The playback is harsh, brittle, compressed and caustic. To be sure, the standard computer recording processor in a conventional computer is designed for conversation and audio purity was never a design factor, but this is the direction that the industry seems to be traveling to. So my question is this...
How can I download quality music on my laptop computer?

Are there chips available that can be installed or outboard devices that can be utilized to accomplish this purpose, and what format (dics, flashdrive, etc.) is preferred?
Your input and suggestions are appreciated.

For music downloading, now most songs can’t be downloaded freely if you are not the subscribers. But you could use some third-party tool to help you get music freely. But you need to know that the music you download are only used by yourself. Here you could use Audio Recorder for Mac to extract audios from videos and other music streaming services. Just take it a try and enjoy more high quality music on your computer.

+1 austinstereo. Download lossless file, use quality playback software, exit computer to outboard DAC. Limitation becomes downstream components (to a point). 
Compressed audio, and highly compressed audio in particular, sounds awful.  However, uncompressed audio, or lossless for that matter, can sound as good or better than any CD.  Provided the right software and hardware is used that is.  
To be fair, iTunes library from Macbook Pro through Dragonfly Jitterbug to good Pangea USB cable to Grand Pre X-1 onboard DAC is more than tolerable. Not equal to FM tuner, but has its merit when Grand Pre tube buffer is active. Now toying with Tidal for downloads and wireless streaming radio through Cambridge 851N network player. Which can't quite match analog FM in the subtleties. Still, best digital yet for me. Soon to try Cambridge CD player through X-1 vs. 851N DACs). 
I get my music from HDTracks.com
all high resolution FLAC files.  They sound amazing! I’ve been purchasing from them for 5 years or more. I use my MacMini and just added an outboard DAC yesterday.  LedZepplin, Metallica, Jazz, Tool, it’s amazing compared to CD.  
I bought an AudioQuest Dragonfly Black for listening to music on my laptop.  I use it primarly when my son is asleep. Otherwise, I now stream Tidal through BluOs on my main system. 
“How can I download quality music on my laptop computer?”

You can certainly do that from sites like HDTracks.com or acousticssounds.com but it won’t matter as long as you’re listening through the laptop computer. The laptop computers are not designed to output high quality and more importantly noise free audio.  
Look into a dedicated streamer like Bluesound Node 2i as a starting point. This device comes with a decent built-in DAC and supports high quality streaming from Tidal and Qobuz.  If downloading music is a priority then consider a Bluesound Vault 2 which allows downloads straight from HDTracks.  
Hard to tell what it is that you want to download.  But in any event, downloading is one step.  Playback is another.  About the easiest and cheapest way to play back from a computer is with an Audioquest Dragonfly.connected to earphones or any player of your choice.
Same thing crossed my mind just reading the title "worth listening to". Same exact thing. However "worth listening to" it may have been going in, by the time it comes out there's just no way. Really good Muzak is about the best you can do. Better than being in an elevator. Or supermarket, even. But "worth listening to"? If that's your goal save your money. But if you can be satisfied with "not nearly so crappy" then you are on the right track.
