When I really need to make myself feel better or shake the cobwebs from my head I play AC/DC.
Rock out to them for 10 minutes and you'll be surprised how energised you will feel.
I have seen AC/DC live on quite a few occasions, though my most memorable gig was when I saw them in 2003.
On my 23rd Birthday me, my dad and some of his rugby mates flew to Germany to see the Rolling Stones supported by the Cranberries and AC/DC. I was the only woman to go but I managed to hold my own quite well.
I could tell you what happened but what goes on in Germany stays in Germany ;)
On that note I will leave you with Let There Be Rock.
To get the full effect turn it up very loud, head bang and play air guitar!!
