Similar artists are very strange. They don't sound even similar. I suppose that the closest to MLTR are Backstreet Boys, but they're also quite different. Some songs sounds like Roxette :) simply great, waiting for a concert in Russia!
"More than a Friend" is one of the most under-recognized songs by MLTR. Same goes for "Complicated Heart". The strong Acoustics, superb melody line and soulful lyrics are all 3 core components that make both of them a Great Song! Thanks for the music!!
