Just curious, it'd actually be awesome if maybe somebody here could help me with a little room project I have planned. I recently moved into a new house, and came up with this great idea as part of my room design to cover one of my walls entirely in record covers. I'm going with record covers because I think just the records would look kinda bland for the most part, give and take some special edition colored discs, and I thought posters were too overdone. Well part of this great idea is I want specific records, and obtaining those records new and even used is gonna be costly as hell.

From the measurements I've done, the wall can fit 66 covers, and I so far have 8. I have a master list of about 75 that I planned to narrow down a little bit (Or I may just spill onto the adjacent walls, I haven't decided yet) but it'd be great if I could get some guidance on the best way to obtain them. While it would be nice to have the discs, truthfully I don't listen to records often, and getting the record covers without the discs themselves would actually be preferable because I assume it'd be cheaper, but I don't know and doubt if it's common for people to ditch the cover slips.

Here's the album list I have, sorry if it's hard to read but it was easier than typing them all out. If anyone could give me any guidance that'd be awesome, thanks guy!
