Hi Alex,
Assuming you have access to mp3, just to give you a cheap taste, take a little listen to Capriccio Italien by Tchaikovsky - certainly not boring or depressing IMO.
You'll probably recognise Barber's Adagio as well as Mahler's 3rd Symphony.
If you like any of these report back and we might be able to suggest some more.
