Thing is, I had a record label at one time. It was a smaller label but we released about 25 different releases and had some national distribution (ie - Tower and Best Buy). We had a couple of releases that had cover www.mycfavisit.com survey tunes and I had to license all of those songs. It took a very long time, It was hard. I had do the same for a good dozen bands whose songs were being used on a couple of projects

Some bands/artists don't care as long as they get paid and contract with an intermediary like the Harry Fox Agency to collect and distribute songwiriting royalties. Other bands require more control (like when I had to go to The Metro in Chicago to physically bring a document to Tesla for sign off...I mean they were very cool and hooked me up with special seating etc).
