2Models in 1 View (Or multiple Models)

Create a view model which exposes both these models as properties.
public class MusicStoreViewModel{

public IEnumerable<MvcMusicStore.Models.Album> Albums{get;set;}
public IEnumerable<MvcMusicStore.Models.Posts> Posts{get;set;}
}

...

@model MusicStoreViewModel

...
foreach(var album in model.Albums)...
foreach(var post in model.Posts)...
