1. Timeless (4,95 stars, 1368 notes)

1. I would rename the diff to Marathon or something like this. So, people will understand what to expect from the map!
2. I would disable letterboxes and the countdown. It's not like they fit with this song or needed here, anyway!
3. Since that a collab, put Collab and Collaboration to the tags.
4. Try to replace SoundCloud with something song related. I don't think that we should put name of this service to the tags.
   Note: why don't you add something like dubstep/broken beat o the tags instead? It might be much more helpful, imo.

1. Do you really want AR9 with 128 BPM song? It's pretty DTable, so I'd go with AR8. Anyway, you're better player than I am (much better ;_;), so it's up to you.
2. 00:27:033 (3,4) - personally, I think you should've mapped the beat on 00:27:267 - a triplet would make your patterns more consistent + it really fits with the piano.
3. 00:36:408 (3,4) - nazi - I would nazi your blankets, but it's a really minor thing and it doesn't matter because the whole map is amazing and this little thing is too hard to notice.
4. 00:55:861 (5) - it sounds TOTALLY different from the previos notes, so I would emphasize it with a new combo!
5. 01:22:814 - feel kinda sad about vocals and drums which are being ignored here.
   Note: and about the piano 01:32:892 - here. Same happens a few more time, for so awesome appers like you guys, it shouldn't take too much time to check your parts for similar mistakes.
6. 01:56:798 - do you know what's polarity? Well, it's an awesome thing + it'd work here, so, please, add a circle at 01:56:798 - to sync with vocals/piano!
7. 02:47:775 (3,5) - the DS looks tricky here, I'm sure that NCs on (3) and (5) would help players to go through this part easily.
8. 02:56:915 (4) - 04:04:298 (5) - there's no such thing as too many NCs! How about another new combo here to point out that transition between the stream and jumpy 1/4 sliders? Players might need it.
   Note: 03:50:705 (1,2,3,4,5,6,7,8,9) - uguu, pretty much the same. Stream with reduced spacing and 1/4 jump are in the same combo, which doesn't look so logical, huh? How about a new combo on (5)?
9. 04:28:908 (2,3,4) - kinda raging on you for using different DS in THE SAME combo for notes with THE SAME sound. Makes me sad, sorry.
10. 05:23:986 (6) - earlier that sound was mapped with a slider. Would like to see a slider here, as well. Sounds like a slider fits here better, try it!
    
    Everything is really well-mapped, except for a few very minor improvements which could be done, from my point of view!

"Not this song again?!?"

1. 3000 ms Audio Lead-In feels kinda long - i'd reduse to 1500-1000.
2. Maybe mentiore at least in Creator's Words who made which part? Thought a little storyboard with mapper's names would be perfect here - i believe you can do it!

1. 00:03:136 (6,7,8) - Last 2 notes would be problem to catch since they starts at blue tick after quite fast 1/8 slider - this can be really big problem with double time or hidden, even with such low OD. I'd recommend to re-arrange rhythm a bit by adding note at 00:03:371 - to make it more intuitive to play - so, try this: (will sounds exactly same but will be much easier to catch)
   
   SPOILER

   
2. 00:06:945 (4,5,6) - Same goes here. Well, since this section was repeated several times i believe you can check & fix all of them by your own.
3. 00:06:965 (4) - This slider is wrongly snapped - it should be 1/6 instead (you may notice this later, at 04:31:271 (6) - starting this part sliders used correct beat snap division). There are lots of wrongly snapped sliders at this part, please resnap them properly
4. 00:15:558 (4) - Make it a bit more curmed for more smooth flow - something like this:
   
   
   SPOILER

   
5. 00:30:090 (1) - Try soft finish instead of whistle? Fits quite nice as for me since new part of song starts here.
6. 00:49:425 (2,3) - Both sliders feels quite unnatural to play. I'd replace them with circles instead
7. 01:13:215 (1) - Try soft finish instead of whistle? Fits quite nice as for me since new part of song starts here.
8. 01:20:363 (7) - Same, on tail
9. 01:28:215 (1) - Same, on head
10. 01:48:840 (1) - This llinear slider feels kinda random and doesn't fit previous pattern. Try to make it smoother, something like this:
    
    
    SPOILER

    
11. 01:54:465 (1,2,3,4) - This short 1/4 slider (2) makes next two notes very hard to catch. I would recommend continiue this section with notes, but if you really want to keep this, try to end this stream with slider instead - like this:

12. 02:20:715 - 02:26:340 - I think placing whistles here at this section directly following piano would be better than placing them only to white ticks - following piano would sounds more natural here.
13. 02:37:121 (7) - This 1/4 slider in the middle of the stream plays bad and doesn't fit the music at all. I'd recommend to replace with 2 notes instead
14. 02:56:925 (1,2,3,4,5) - This 1/4 sliderjump section plays kinda bad and does not feels right here. I would recommend keep consistent spacing here but slighty re-arrange placement, maybe something like this?
    
    
    SPOILER

    
15. 03:36:183 (3,4,5) - Noticeable stacking issue here (it also breaks osu! stacking and may confuse players, please fix that)
16. 03:50:011 (8) - Missing claps on repeats
17. 03:53:761 (5) - ^
18. 03:57:570 (6) - Missing claps again.
19. 04:14:621 (6) - This short 1/4 repeat does not flows nice and may confuse people this part (it is very easy to get 100 here) - i would recommend to simple replace it with notes.
20. 04:19:191 (4) - This slider should starts at 04:19:308 - to follow drums properly, linke this: (also having it on white tick instead of blue will made it much easier to catch)
    
    
    SPOILER

    
21. 04:22:121 (6) - Replacing with 2 notes would improve playability of this part
22. 04:48:381 (6) - Try to re-arrange it a bit for better flow - something like this:

23. 05:41:350 (1) - Add finish to emphazire this part and remove whistle
24. 05:48:850 (1) - ^
25. 05:56:350 (1) - ^
26. 06:18:860 - Add fadeout spinner perhaps?
