It's always a challenge for a band to take on a cover song. Not only do you have to make sure you do justice to what is already a classic, but you also have to make sure that you put your own spin on it so that you're not just copy-and-pasting someone else's work as your own. Some bands are more than worthy of the challenge, but every so often there's a few that are in way over their heads.
Regardless of which subcategory they fall into, each of these songs has ended up disappointing the rock crowd by not living up to their expectations. While they don't hit the mark, that's not to say that these bands are all bad. The songs themselves may be god awful, but oftentimes it just comes down to meshing genres in a way that just didn't work.
On the other hand, there are people who just want to screw around and do borderline karaoke versions of the original songs, which end up making even the original classics hard to listen to. There may have been a ton of potential at play here, but it takes a certain level of incompetence to screw something up this royally.
I'm just a junkie for all things media. Whether it's music, movies, TV, or just other reviews, I absolutely adore this stuff. But music was my first love, and I love having the opportunity to share it with you good people.
