do any of you ride with bicycle speakers? something to strap to the handlebars or on the top tube or whatever?

i do 40+ mile bike rides with the wifey on sundays, and we were both thinking it would be fun to have some music playing. we mainly ride this long bike trail, and do laps on it (its 5 miles to the trail, then the trail is 10 miles)...

we got the the idea from this roadie we see all the time on the trail. he has a speaker on his bike. its not super loud but we sometimes try to catch up with him to listen.
I dubbed him "Ferrari Santana"....because he has this sporty looking red and white newer road bike, and he has a matching kit. and the first time we saw him he was listening to Santana. so everytime we see him its like "OMG its Ferrari Santana!!! lets try to catch up to him!" lol

anywho, im sure some of you might think speakers on bikes is kind of lame, but i think it would be a fun thing to have....
