Yes, often there will be recommendations of more obscure bands or music that isn't for the average person. That should be expected. Recommending Journey, Taylor Swift or even U2 is useless. Everyone has heard and knows their music. Heck, my 18 year old son has retro'd back to music by Stevie Wonder, Journey and Boston.
If my sons weren't introducing me to current stuff, I'd be bored to death of today's popular tunes. I have a hard time listening to the stuff I over-listened to in my past.
