Led Zeppelin-Black Dog

This song is a great pick me up and gets I find gets me going at the start of an early morning.
Performed live, there's a great little adlib of another great track 'Night on the tiles' at the beginning.

Tchaikovsky-1812 Overture

I first heard this in music class when I was 10. It made me realise that Classical Music is not at all boring.
It can evoke different emotions at various stages during just once piece. 1812 is a perfect example of this.
I really enjoy listening to Classical Music and I'm particularly fond of it as it helped me go to sleep when I had a few months when I struggled to sleep. It calmed me down which again, shows how Classical Music can affect you. Here's the whole thing but in 2 parts.
