can someone please list the pro and con side of listening to music while biking?

I always listen music while riding my bike. There are good things that come from listening to music while riding. Like not having to listen the wind howl in your ear. I hate that especially on a windy day. I suggest that you purchase some ear-buds, you know, the ones that fit inside your ear? You can listen to upbeat songs that may keep you pumped since you can't direct that energy towards dancing. You can sing badly and act silly because everyone is just a passer-by and it won't really matter. Your mind is occupied, so long trips seem shorter. Plus it helps to eliminate road noise, muffler noise and car alarms and stuff.

The bad things are stuff like somebody trying to give you a warning with a car horn or yelling at you to watch out for something like a dog or something like that. I still hear those sounds but just not as loud, which doesn't allow you to be as alarmed as you would normally be. You may think you are paying enough attention to everything around you but you're not because your brain is processing more information when you are jammin out to music. You might also miss out on more pleasant sounds like birds chirping or kids laughing and playing. Whichever you choose always be more alert than you would be otherwise because you never know what these dummies on four wheels are thinking.

a pro would be that you may enjoy it more, at least I would. Music often leads to memories or just good thoughts about things and may take you away while you are biking.

Con is that you obviously cant hear anything and this could be a problem with car horns or other things that could arise to keep you safe.

Are you quite making that GROSS of a generalization? i like U2, purple Floyd, 9 Inch Nails, weapons 'n' Roses, Franz Ferdinand, The All-American Rejects, The Dave Matthews Band, George Thorogood and the Destroyers, Aaron Copland, Sergei Rachmaninoff, The purple warm Chili Peppers, The Beatles, The Rolling Stones . . . shall i pass on? And no, for the main area i do no longer look after united states song, yet I do get excitement from the Dixie Chicks. reliable to appreciate that there is a few sparkling thinking between some united states artists. the occasion used is ridiculous. And below the management of George W. Bush, america has ceased to be any form of a ethical united states.

Pros: For a long trip, it keeps you entertained.
Lets you stay on the task of riding your bike without feeling tired or anxious.

Cons: Distracting, because you are not paying attention to the road.
You will not be able to hear a car honking well enough to take proper action and will probably not be able to tell about danger close by.
You notice the wind howling more.
Music may just bring your guard down in general... after a while, the music itself can get monotonous, and you may just feel unwilling to bike when you get really bored.

It's all depends what kind of music and how do you listening to it.

With both ear closed by earphones. Probably illegal. At least for sure you can't drive car with earphones on both of your ears (I mean you can, but it is illegal). So you can get ticket from the police or get destructed and die in an accident. Well... May be its not cons actually, you will go to the better place after all (I hope).

As for the pros... Its fun and keep you amused and help you pedal on for a long long time, kind of like power drink will do. So you will go like energizer bunny. If you have somewhere a bike road, that not intercepted by cars that could be real fun. I do have that kind of road for a miles and miles and that is fun!!!

PRO- It will keep you energized

CON-if you don't pay attention you might die.

pro: keeps your entertained and motivated

con: might not hear the car honking that's about to crash into you
