ugh that's a tough one. both songs have one important word - "LOVE".
My Love - romantic. here's another song dedicated for Linda, but McCulloch's solo is the best part of the song.
Beware my love - Kick-ass and should be theme-song for a great action flick, very fits where the car chases or something like that... but the song gets boring everytime.
My Love for the first time wins here, although I disliked a bit, but... still it's a Macca.
