Been searching long and hard for a solution for this problem. As we are aware the normal standard loading routines on a stock C64 cannot handle programs over 202 blocks in size.
These SID songs (converted to PRG with PSID64 and compressed with Exomizer) was all unable to load properly by standard ways on C64 (tried MMC64, and loading from SD2IEC, would suspect the same result if loaded from a real physical 1541 drive too).
SOLUTION #1 - For real Floppy Drive (1541)
The "loader" found in the Action Replay MK 4 cartridge can do so. The loader.prg is a 1016 bytes long thinghy that you can select with cursor keys and press return in order to load those cumbersome HVSC RSID (chop off 124 bytes, then save as .PRG) and let them load without errors and play nice :-)
You dont even need to Action Replay cartridge connected to C64 at all, simply just the special loader.
It should be pointed out that this loader and procedure will eventually end up as an D64 image. The D64 image mounted on my SD2IEC *does not* work with the MK4 loader (a quick flash of the led, then just stops loading), but the D64 image and loading works fine in emulators and real 1541 floppy drive connected to a real Commodore 64.
Straight from the Action Replay manual:
LOADING WITHOUT THE CARTRIDGE PRESENT
1. LOAD"LOADER",8 and RUN. The Loader must previously have been saved to the disk.
2. Move the cursor over the name of the file and press RETURN.
Programs over 202 blocks in length, and all Warp*25 files must be loaded either by the cartridge or the Loader. No alternative loading system can handle Warp files, but some can handle long, normal format files. Shorter programs and two part programs saved by the standard Save option can be loaded by the normal CBM kernal, or any sensibly written hardware based disk fastloader. If a two part program is loaded by the loader only the first part will load at high speed.
NOTE: The LOADER does not work with the 1581 drive.

In addition, its best to compress the SID PRG too with Exomizer to keep the space at minimum. Keep in mind that I'm not interrested in any fast loading / fastloaders or the Warp*25 fast loader mentioned, as the SOASC= ROTS project has time to wait for loading. But, unable to load them into memory successfully = is a direct show-stopper for recording!
SOLUTION #2 - For SD2IEC and real Floppy Drive (1541)
I found a different loader called "loader/ac.replay" ("**** ACTION REPLAY 3.0 LOADER ****), which does actually work well with D64 mounted on a SD2IEC, with directory and loading. But, the "TURBO OFF" mode had to be set for atleast SD2IEC in order to load the tunes properly, decompress and play as intended.
You dont even need to Action Replay cartridge connected to C64 at all, simply just the special loader.
Follow my routines, screenshots and programs below to do this yourselves. Finally somebody can make some sense out of this and present it clearly for everybody to understand :-)
The too-large SIDS in HVSC
The following files below are references to huge and over 202 blocks SID files. 202 blocks are the same as 51200 bytes. Basically memory from $0800 to $D000. It should be noted that the block sizes below are for the compressed Exomized version, not the original SID PRG filesize.
