Original sentence: However, these songs are not all identical to the versions that appear on the original albums -- on this album, the songs generally are presented in much higher sound fidelity, and some songs have been rearranged
Edited sentence: For example, "Last Call For Rock 'N' Roll" appeared as "Mama's Little Angels" on Quiet Riot; the music is basically the same but the lyrics are completely different.However, these songs are not all identical to the versions that appear on the original albums -- on this album, the songs generally have a substantially better sound quality, and some songs have been rearranged.In any case, it is definitely worth buying as it showcases some of the things that would later appear on Ozzy Osbourne's first two solo albums, which featured Randy Rhoads as guitarist, and also exhibits the differences in style between his work with both bands.This may be seen as a disadvantage if looking for the exact duplicate of the original, or as an advantage if preferring to hear more than one version of the song
