Thought I would share this link with you:
AKM Music MP3 Downloads of Copyright Free Music and Royalty Free Music Library
This is probably the best website I have come across for low cost stock music that is non-cheesy - pretty hard to find nowadays. Go to the download section and you can download a decent track for about £10.
Note: I have no affiliation with this site what-so-ever. Just thought id share as it is something I will be using a lot of in the future. Check out the underscore section if you are doing some corporate work, some pretty nice tunes on there.
