Antidote to broken promisses

.
Years ago, I promised someone I'd send them music from one of my favourite bands. I had some of it in mp3 (don't actually remember where from), but most of it was out of my reach (couldn't find it to download it, didn't have money for original CDs for a long, long time). And while I sent several gigabytes of music to this person years ago, I decided not to include these mp3s (bit of a perfectionist, I am) and decided I would rather send the music in original CDs as soon as I could afford them.
A few months ago, I started working and earned some money. Part of that money was, of course, immediately put aside for purchasing this music in hopes of finally keeping my promise. And so, I travelled the country far and wide in order to complete the entire discography (some of the albums are pretty old by now and since the band is quite popular here, they are difficult to acquire). They were supposed to be sent in a form of a birthday present. There was even a card made (from scratch). Not a bad one, if I might add.
But somehow, again, things got complicated and keeping this promise of mine didn't seem to be appropriate anymore, for several reasons I won't discuss here, and fair towards several people I don't wish to mention here either.

So, now, I have a whole collection of CDs of one of my favourite bands, wrapped (I had the stores remove the plastic wrappings with the price tags on them and rewrap them) and in a plastic bag on my desk, birthday card right next to it. It has been sitting there for months now, collecting dust, since I simply don't know what to do with it.
A part of me desperately wants to simply unwrap the whole damn thing and just enjoy the wonderful music, while the other part of me insits I keep it intact (don't ask me why).

So in the end, I have something that does and does not belong to me at the same time. And oddly enough, the more time goes by, the less urged I feel towards claiming the CDs as my own and the more satisfied I feel with them just sitting there on the corner of my desk, collecting dust.
