I have always played a lot of covers. I really enjoy learning who wrote a song, who recorded the original and hearing others who have recorded covers. There's often quite a progression of ideas and mutations (think "Train Kept A Rolling as it progressed from Tiny Bradshaw's original recording up through Aerosmith's rendition). I just found this site "SecondHandSongs". I'm not posting a url because I'm not sure regarding TalkBass policies on this topic, but you can easily Google it. It's not a great web site (loaded with ads) but the information is priceless. You can find that contemporaneous Finnish cover of that pop hit you've been playing for decades. It also links to YouTube and Spotify recordings of the songs.
