It's underrated but bonus track material, instead the should have placed "Alone" right there on the tracklist.
It's not bad at all though, I like the dark edgy vibe.
The one who put Alone on the bonus tracks list should be arrested.
When I know what kind of gems are among Kelly's unreleased tracks, I don't get how could this be included on the tracklist... Still, they are much worse tracks (not on Stronger, I mean in the universe).
