Is there a database online where i can search for a piece of music/song and check whether it has been featured in any films? Whether it was a title track or supplementary?

Thanks.

Would be a nice addition to IMDB, but alas, not there right now.
I don't think there is such a site yet. There was a mention of
a site not too long ago here on the forum regarding licensing of
music with searchable databases, but I can't seem to locate it
now.
