Soundtracks.

[Resistiv]

Eh, it can be useful to people who are in need of sound effects that they remember from iconic games, so it's understandably confusing if you go in to browse randomly instead of with specific intent. However, if you want you can upload soundtracks to sites like YouTube (as I do) if they don't already exist there (or are horribly outdated). In most cases, it actually provides more exposure for the soundtrack and allows for better organization.
