In my late teen years when I had a driving license I would pick up my my college friends and go for a drive listening to happy hardcore songs, DJ cammy being a favourite.
I'm now in my late 20's and only still friends with one of these ladies but we often reminisce about these times together.
After a chat tonight with her and with my DP being out at the pub with friends I decided to put some of our 'old' songs on, and I feel so happy 
even at my age, no longer a teenager, they are still feel good happy songs, or is this just me because of old memories...
