Although not specified as such on the cover this budget priced release on the Spectrum Music label (a division of Universal) is a compilation of previously released tracks from Katherine's six album deal with Universal Classics. Compilations of course being the only way the label can continue to profit from her lucrative five year partnership with them since her decision to leave and continue her career with the Warner label.
Of the fourteen songs, five are from Premiere, one from Second Nature, one from Living a Dream, three from Serenade, two from Rejoice and one from Sacred Arias. The exception is a variation to the album version of Somewhere over the Rainbow - the one here is a live recording from a 2009 Friday Night is Music Night concert.
So this 2011 release offers nothing new to the Katherine Jenkins fan apart from a different version of Over the Rainbow, unless of course the four page biography reveals anything new about the singer which we don't know already, and not surprisingly it doesn't.
The appeal therefore is to those who don't own the back catalogue and simply want a Best Of Katherine songs. For this purpose Sweetest Love perfectly complements The Ultimate Collection which presents the later albums whereas this one leans towards the earlier years of her recording career.
