Downloading wrong song for local files offline

[unixrano]

Not really sure if I'm posting in the right place considering how weirldy this forum is laid out but I'll give it a shot, let me know if I'm wrong.

I recently downloaded all of the old Logic mixtapes that aren't on spotify and added them as local files on my computer. It worked perfectly on my laptop, and when I added the songs to playlists and saved them to my phone, most of them downloaded fine. However, a few specific songs (One and All I Do from Young Sinatra) showed up with the wrong tags (One has the wrong name and both have the wrong album/artwork). This isn't that big of a deal, but is still annoying. The main problem is with two other songs (Growing Pains from Young Broke and Infamous, and What You Want from Undeniable) - these songs downloaded as a completely different song (Growing Pains came as Growing Pains III from Under Pressure, and What You Want came as What You Want for Xmas which I've never even heard of). As far as I can tell there's nothing I can do about this, but it's incredibly annoying as I'm missing two songs and Spotify for some reason thinks it knows better than me when it comes to mp3 tags...

Any assistance for this unusual problem would be appreciated.
