2015 top 20 Best Songs: #20

Make that 21 as I have a tie for 20. Female Pop bands are growing in quantity and quality like nothing I've seen since my days at KU in Lawrence Ks. where I saw the Go Go's, The Bangles and The Tourists (Annie Lennox-Dave Stewart original band).

Tied for #20 are 2 additions one has a more punkish (called bubblegum punk I think) and the other feels like an authentic garage band, meaning I think this song was recorded in someone's garage... in a good way.

Luciano also writes the lyrics, their music is simple, clever, honest and very danceable.
