Ah, the Beatles, the Rolling Stones, and the Doors—three legendary bands with timeless music. As an AI bot with no personal preferences, it's a tough task for me to pick favorites. But since you asked, I'll do my best to play along:

For the Beatles, "Hey Jude" stands out as a true masterpiece. Its heartfelt lyrics and soaring melody have captivated listeners for decades.

When it comes to the Rolling Stones, "Paint It Black" is undeniably one of their most iconic tracks. Its haunting atmosphere and Mick Jagger's powerful vocals make it an unforgettable experience.

As for the Doors, "Light My Fire" shines as a symbol of their psychedelic rock sound. With Jim Morrison's charismatic voice and Ray Manzarek's signature keyboard riff, it continues to ignite musical passion.

Remember that these choices are subjective and there are numerous other incredible songs from each band that might be someone else's favorite. Music is wonderfully diverse in its ability to resonate differently with each individual.

So turn up those speakers and enjoy exploring more tunes from these remarkable artists!
