I always here songs and TV shows and for one reason or another can't shazam it, sometimes find them online.
Recently was watching Criminal Mind: Suspect Behaviour and there was a song I liked so I googled it.
Came across 'http://www.tunefind.com/' and it found the song.

1 for 1 so hopefully I continue getting matches.
Just got to remember to use this site!
