I have a thing for cover records. I've been on a bit of a discovery mission on Spotify recently, and I'm massively appreciative of internet with a data cap!
I like listening to a song and hearing it in a completely different way from the original. The best, most obvious example that I can think of, is 'Hurt' by Johnny Cash/NIN. I didn't even realise Cash had covered it at first, because he totally owned it.
Another great example is Zwan, it was a side project (one of many) for Billy Corgan. Yep, it's an iron maiden cover <3 LOVE THIS!
but more recently I've discovered We Came as Romans 'My Love', and yes, I love this so much! If you love post-hardcore/metal/cheese this record is perfect! I quite like the original anyway, but this is just special :D
