If you count the songs you will get the sum of 88. But then, on both "rockin' up" and "rock-hard & soul" are remixes of formally published songs. Also, on "rock-hard & soul" one particular song occurs twice, once in the 'rock' version, once just accompanied on an acoustic guitar. Hence, there are 'only' 70 original songs.

(while you're listening maybe keep in mind that Youtube pays the artists even less than Spotify - but it's easier accessible. Should you like a particular song please buy a download from Amazon or CD-Baby)
