There are some songs that are so amazing. They touch you on an emotional level and you can listen to them 50 times in a row and you just have to hit "play" one more time.
Coldplay does a great job with the original, but I like this cover. The harmonies send shivers down my spine.
There are so many covers of this Lenard Cohn song, but Jeff Buckley's version is classic to me.
So what are your favorites? The songs you just can't get enough of hearing.
