IMO, the original post can be seen two ways:
1) The new Maroon 5 is not near as good as the old Maroon 5 or just plain bad, period.
2) Radio is not any good and irritating (especially in Malaysia)
I can't address Maroon 5's history in detail but more on M5 later.
Personally, if I have a choice I won't listen to (new term I heard used recently) "terrestrial radio", i.e. traditional AM/FM. It's just irritating and tends to put me in a worse mood than I have before listening to it. Therefore I prefer silence over trad. radio if no other choices are available. Having said that, I have a young daughter who isn't into gangster rap or music that has an 'Explicit.." label attached who I usually let have free reign over car radio. This results in the sometimes maddening button pushing but always resulting in either Radio Disney or some other pop/rock selection. I have asked her to change the channel when songs that truly annoy me come on. Two examples would be the recent Justin Timberlake hit (whatever that is) in mega-heavy rotation (especially on Disney) but also some beaten to death classic rock like "Old Time Rock and Roll". I have my reasons for both requests although different.
Bottom line is that I just can't enjoy radio in the car except for maybe every 30-100th song played. One of those that gets a nod may be "This Love" by Maroon 5. But driving this morning with her I heard some of the new M5 and it sounded like some of the other accurate but depressing descriptions in this post. So be it. Not an Adam Levine or 'The Voice' fan so no love lost.
When alone in the car, I have come up with a solution that works at least for me. I have Pandora on my iPhone with at least 20 different "stations" I've created. Even personalized, style/artist/song directed stations can have duds for my ears, so having the "thumbs down/up" feature helps me to tailor those stations. Also being able to advance to the next song or switch stations frees me from the tyranny of the trad. radio playlist and programming. It's also available when in front of my computer so it works OK.
Actually, my recent iTunes purchases have all been from listening to Pandora stations, hearing some new music, making a note and then buying the song or album. I know there are issues like the ads or that artists don't make as much on Pandora plays as trad. radio. Still it's heads and tails above trad. radio.
The truth is that barring some major change, trad. radio is dead to me and I'll avoid it when there are alternatives like Pandora or my own collection of portable music via iPhone or iPod. Or podcasts. Or audio books. Or silence.
I don't know what solution there is for M5 not retaining a favorable direction. That's their choice and as much as I don't like their current music, I like the fact that in America you can make whatever musical or business choices you want and get paid respectively via money, satisfaction or even that lousy feeling when you've sold out (no experience with that personally BTW).
I also don't know how or if internet based radio stations or services like Pandora or Spotify are available in Malaysia. If they are, the OP is in luck and shouldn't spend one more minute listening to bad music while supporting their advertisers. Get on an internet device and start listening to music more in line with your ears.
If it's not available.....start planning your trip (immigration?) to the U.S.
