There are stunning similarities between HR & Anu Malik.
Both of them use surprisingly similar rhythms & modes,
At times it is very difficult to say whose composition is this.(among them)
, if you don't believe me go to any site and listen to their songs one after another, it gets mixed up in brain.
Like AM, HR keeps changing his style of music and therfore doesn't leave any signature mark on songs( in plain terms it means using certain instruments in such a way that you always realise on listening to a song, who is the composer, like AR Rehman, JL do.
None of them have been trained in classical music.
HR picks up flot from Latin & Spanish music, just like AM (sorry inspiration!)
Both of them have strange fascination for sequencer rhythm & playing bass guitar effect on keyboards.
Both avoid Lataji & Ashaji.
Both of tham have been vastly successful commercially and know how to change with time.
There is one strong difference, while AM has struggled a lot in 80s HR always had a smooth sail. Despite being unsuccesful initially,
he kept getting movies.
My opinion only..... please don't lash out.
