You should be aware that if you put redirects in WP to make it load itself inside a frame, google may not index the wp page. Not 100% sure about this so you should check.

Create your wp site inside a framed site. One window for the music and another for your main site.
But when someone finds a page of your main site in a search engine and follows the link to it, it will load outside of the frame wrapper so the page has to redirect to the framed page telling it to load that page in the main site window. It’s a pain to implement which is why no one does it.

And note how its sets WP_MEMORY_LIMIT to an integer value as the manual says it should be meaning no M after it. The M works in php.ini but not in php code.

uploads will be using the GD library functions to process images (unless you have some plugin using imagemagick).

GD functions can be memory intensive and will grab plenty, especially for bigger images such that even doing a copyresampled will cause it to fail. And the reason it fails is because hosting providers put a limit on how much memeory each script can grab.

There are several ways to up that limit but not all of them will work depending on other restrictions your host puts on your account.

You can either change memory_limit in your php-ini file but this is not recommended because it means any script you run can grab that amount of memory.

You can put it in your .htacess file but this won’t work unless your host has enabled it and is not recommended for same reason as changing php_ini.
To check if yuor host has enabled it you need to run a script on your host which calls php_info() and check the the configuration which should include -enable-memory-limit.
If it doesn’t include that enable command then you are stuffed unless you can change php-ini.

If it does include that enable, then the best way to increase memory is to include the following in the script causing the problem.

<?php ini_set(memory_limit,64); ?>

note that there is no M after the amount of memory.

also note that if you are on shared hosting and strting grabbing lots of memory your host might kick you off which is why they limit memory so there is plenty for everyone.

Simplest answer of all is to resize images before upload to sensible sizes and then GD function won’t blow its guts.
