Please put down the Chalupa!
I not sure what to think about the person who selects the music tracks at live sporting events (ya know, the music that happens in between plays) . . . but if I hear "Pump Up The Jam" or "Paradise City" or "Enter Sandman" one more time . . . I will commit ritual seppuku.
Sure, you were in a high school rock band, maybe even the #1 DJ at Camp Manatawanda . . . but just because you have an iPod now like the rest of us that you listen to on your morning commute doesn't make you a music maven. When it comes to public and professional projects, enlisting the help of a good music supervisor is often times a really good idea.
Solid music supervisors have access to and command of a vast catalog of music, have musical knowledge and experience, are keenly aware of emerging and popular trends and TASTE. Their job, day in day out, is to help you find and narrow down an appropriate selection of music for your film, television show, advertisement, video or live events, and their most important job is to make you (their client) look great!
Now, I am not advocating not conducting your own music searches. For those of us who have the time and love being involved in the creative process (and that's most of us), combing through the online music search tools and auditioning tons of library tracks are terrific ways to jumpstart the music selection process . . . but when you start getting a sense of the creative direction . . . that's a great point to bounce it off the people who live and breathe to help you make decisions on music. Moreover, share the music that you found in your search with them as its always a good way to help them get on the same page so they can nail it for you!
