There's an easy way to do what you want.

Don't be a cheap ass and buy Spotify.

Sometimes, we don't need a reason to do things. Multiple people here have suggested things you can do, which you shot down all of them, so I respond. Is there a way to do what you want? Absolutely.

I said neither of those things. I know exactly how to do what you want to do, I also know that you're allowed to figure it out on your own. I don't care what music or how much you download, I grew up in the height of Napster and kazaa and limewire.

If you aren't willing to either listen for free with ads, or pay like 10 bucks a month, then no, you're doing it the only way possible. Figure it out.
