My Question or Issue

I've been using Musify, a music downloader, to download and save all my music on Spotify. It has occurred to me that I've been hearing wrong songs being downloaded via Spotify's Share option (Share/Copy Album Link). I've been seeing repeated songs with different titles in the same album, obviously wrong songs that differ from those played directly on Spotify (which I'm certain that those played on Spotify are correct), and/or songs that look like a different version of the original ones. 

At this moment, I'm not able to reach Musify's support (its website apparently suspended?) and I was wondering if there's a chance that Spotify has been giving wrong links for a certain titles.

Please let me know how I can work things around for this issue. Many Thanks.
